The Qur’anic Root W S ʿ
From spaciousness to capacity, ability and encompassing
The Qur’anic uses of و س ع are connected by an image of ample room as opposed to constriction. The earth can be واسعة, offering room to move and live; a person has the ability to act within their وسع; and their wealth and resources can be described through سعة. This semantic connection does not by itself establish the historical order in which the usages developed.
The same image remains in broader applications. Knowledge can encompass everything, mercy can embrace everything, and واسع describes The God in contexts involving bounty, giving, sufficiency, knowledge or provision of ample means.
The shared meaning is therefore better understood as more than “bigness” or simply “encompassing”:
W S ʿ: spaciousness, room and capacity. In the Qur’an, this semantic field includes the breadth of the earth, human ability, ample resources and encompassing through knowledge and mercy. Context determines the kind and scope of that breadth.
This family occurs 32 times in the Qur’an: 6 instances of the verb وَسِعَ, 6 of the noun سَعَة, 5 of وُسْع, 9 of وَاسِع, 4 of its feminine form وَاسِعَة, and 2 of the Form IV active participle مُوسِع. Wāsiʿ and wāsiʿah are gender forms of one description; these six counting categories are not six independent morphological patterns.
Qur’anic forms
Spaciousness in pre-Qur’anic Arabic poetry
Poetry transmitted from pre-Islamic poets uses this family both for ample space and for a sense of ease. The evidence here is the use of the word in the poetry itself.
The pre-Islamic poet al-Rabīʿ ibn Ziyād al-ʿAbsī addresses al-Nuʿmān in verses transmitted in Kitāb al-Aghānī with the following reading:
لَئِنْ رَحَلَتْ جِمَالِي إِنَّ لِي سَعَةً
مَا مِثْلُهَا سَعَةٌ عَرْضًا وَلَا طُولَا
“If my camels depart, I have ample room, unmatched in breadth or length.”
سعة appears with “breadth” and “length”; the following verses also mention pasture. The poet speaks of room and resources for living elsewhere. The spatial image is clear, although the verse belongs to a boast of independence from the court.
The pre-Islamic poet al-Nābigha al-Dhubyānī says in the poem beginning “Min āli Mayyata rāʾiḥun aw mughtadī”:
تَسَعُ الْبِلَادُ إِذَا أَتَيْتُكَ زَائِرًا
وَإِذَا هَجَرْتُكَ ضَاقَ عَنِّي مَقْعَدِي
“When I come to visit you, the lands open wide for me; when I leave you, even my own seat becomes too narrow for me.”
Here تسع contrasts with ضاق. The place does not physically change its dimensions: the poet expresses feelings of ease and constriction through the image of space. The usage connects spatial breadth with human experience.
These two transmitted examples of pre-Islamic poetry show a connection between ample space and a sense of ease. They do not establish every meaning of the family or reconstruct the historical sequence of its development.
“My earth is spacious”: open space
One of the clearest Qur’anic applications concerns the earth:
يَا عِبَادِيَ الَّذِينَ آمَنُوا إِنَّ أَرْضِي وَاسِعَةٌ فَإِيَّايَ فَاعْبُدُونِ
“O My servants who have believed, My earth is indeed spacious; so worship Me alone.”
Al-ʿAnkabūt 29:56
Here واسعة closely expresses spatial breadth. The earth is not confined to one spot in which a person must remain.
The earth receives the same description in al-Nisāʾ 4:97 and al-Zumar 39:10.
In these uses, wāsiʿ does not carry a vague philosophical meaning of “infinite.” The earth has breadth and room for movement and finding another place.
This spatial use provides a clear image of ample room. To understand the other applications, we must identify what each verse describes as broad or encompassing.
“Wasiʿa kursiyyuhu”: capacity and encompassing
The Verse of the Kursī states:
اللَّهُ لَا إِلَٰهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ ۚ لَا تَأْخُذُهُ سِنَةٌ وَلَا نَوْمٌ ۚ لَهُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ ۗ مَنْ ذَا الَّذِي يَشْفَعُ عِنْدَهُ إِلَّا بِإِذْنِهِ ۚ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ ۖ وَلَا يُحِيطُونَ بِشَيْءٍ مِنْ عِلْمِهِ إِلَّا بِمَا شَاءَ ۚ وَسِعَ كُرْسِيُّهُ السَّمَاوَاتِ وَالْأَرْضَ ۖ وَلَا يَئُودُهُ حِفْظُهُمَا ۚ وَهُوَ الْعَلِيُّ الْعَظِيمُ
“The God—there is no deity except Him, the Living, the Sustainer. Neither drowsiness nor sleep overtakes Him. To Him belongs whatever is in the heavens and whatever is on earth. Who can intercede with Him except by His permission? He knows what is before them and what is behind them, and they encompass nothing of His knowledge except what He wills. His kursī encompasses the heavens and the earth, and preserving them does not burden Him. He is the Most High, the Great.”
Al-Baqarah 2:255
وَسِعَ كُرْسِيُّهُ السَّمَاوَاتِ وَالْأَرْضَ presents the kursī as encompassing the heavens and the earth: they lie within its scope, without exceeding its capacity.
The root و س ع, however, does not determine the nature of كرسي. The precise referent of kursī in this verse is a separate question. Wasiʿa itself conveys the relationship of capacity and encompassing.
This verse also shows semantic overlap between wasiʿa and encompassing expressed through إحاطة, without making them interchangeable in every context. Wasiʿa approaches encompassing through having room for something and accommodating it.
The reach of knowledge and mercy
Ṭā Hā states:
إِنَّمَا إِلَٰهُكُمُ اللَّهُ الَّذِي لَا إِلَٰهَ إِلَّا هُوَ وَسِعَ كُلَّ شَيْءٍ عِلْمًا
“Your deity is only The God, besides whom there is no deity. He encompasses everything in knowledge.”
Ṭā Hā 20:98
عِلْمًا is crucial. The verse does not say that The God spatially contains everything. The sentence itself identifies knowledge as the domain of encompassing.
The same construction appears in al-Anʿām 6:80 and al-Aʿrāf 7:89.
Al-Aʿrāf 7:156 states وَرَحْمَتِي وَسِعَتْ كُلَّ شَيْءٍ, “And My mercy encompasses everything.” Al-Anʿām also states:
فَإِنْ كَذَّبُوكَ فَقُلْ رَبُّكُمْ ذُو رَحْمَةٍ وَاسِعَةٍ وَلَا يُرَدُّ بَأْسُهُ عَنِ الْقَوْمِ الْمُجْرِمِينَ
“If they deny you, say: Your Lord possesses encompassing mercy, and His severity will not be turned away from the offending people.”
Al-Anʿām 6:147
Here واسعة describes mercy itself. Mercy is not restricted to embracing only a small circle.
In Ghāfir 40:7, mercy and knowledge occur together: رَبَّنَا وَسِعْتَ كُلَّ شَيْءٍ رَحْمَةً وَعِلْمًا, “Our Lord, You encompass everything in mercy and knowledge.”
When this family accompanies knowledge and mercy, the sentence identifies the dimension of encompassing. The root alone should not be made into a theory about space or the nature of existence.
“Wusʿ”: the capacity within which a charge can be borne
An important Qur’anic form is وُسْع. It occurs five times, each in a construction limiting what a person is charged with to their capacity: al-Baqarah 2:233 and 2:286, al-Anʿām 6:152, al-Aʿrāf 7:42 and al-Muʾminūn 23:62.
A well-known example closes al-Baqarah:
لَا يُكَلِّفُ اللَّهُ نَفْسًا إِلَّا وُسْعَهَا ۚ لَهَا مَا كَسَبَتْ وَعَلَيْهَا مَا اكْتَسَبَتْ ۗ رَبَّنَا لَا تُؤَاخِذْنَا إِنْ نَسِينَا أَوْ أَخْطَأْنَا ۚ رَبَّنَا وَلَا تَحْمِلْ عَلَيْنَا إِصْرًا كَمَا حَمَلْتَهُ عَلَى الَّذِينَ مِنْ قَبْلِنَا ۚ رَبَّنَا وَلَا تُحَمِّلْنَا مَا لَا طَاقَةَ لَنَا بِهِ ۖ وَاعْفُ عَنَّا وَاغْفِرْ لَنَا وَارْحَمْنَا ۚ أَنْتَ مَوْلَانَا فَانْصُرْنَا عَلَى الْقَوْمِ الْكَافِرِينَ
“The God charges no soul beyond its capacity. What it has earned is to its benefit, and what it has acquired is against it. Our Lord, do not take us to task if we forget or make a mistake. Our Lord, do not lay upon us a heavy burden as You laid upon those before us. Our Lord, do not impose upon us what we have no strength to bear. Pardon us, forgive us and have mercy on us. You are our protector, so help us against the disbelieving people.”
Al-Baqarah 2:286
The root’s image remains discernible: a charge must fit within a person’s capacity, rather than exceed the room available to bear it.
In this way, wusʿ expresses ability and capacity.
The root alone cannot establish a technical ratio such as “wusʿ is always less than ṭāqah.”
Al-Baqarah 2:286 itself contains both words:
At the beginning: وُسْعَهَا
And towards the end: مَا لَا طَاقَةَ لَنَا بِهِ
The verse uses two different expressions, but it does not by itself establish that wusʿ is always a degree below the utmost limit of endurance.
What is clearer about wusʿ is the available capacity to do or bear something.
“Saʿah”: from ample room to resources and wealth
سعة belongs to the same field of breadth, but has several Qur’anic applications.
Sometimes it explicitly concerns wealth. Ṭālūt’s opponents object that he has not been given سعة من المال, ample wealth or financial resources. The expression occurs in al-Baqarah 2:247.
Al-Ṭalāq states:
لِيُنْفِقْ ذُو سَعَةٍ مِنْ سَعَتِهِ ۖ وَمَنْ قُدِرَ عَلَيْهِ رِزْقُهُ فَلْيُنْفِقْ مِمَّا آتَاهُ اللَّهُ ۚ لَا يُكَلِّفُ اللَّهُ نَفْسًا إِلَّا مَا آتَاهَا ۚ سَيَجْعَلُ اللَّهُ بَعْدَ عُسْرٍ يُسْرًا
“Let someone of ample means spend from their abundance. Whoever has their provision restricted should spend from what The God has given them. The God charges no soul beyond what He has given it. The God will bring ease after hardship.”
Al-Ṭalāq 65:7
Here ذو سعة is someone whose resources allow greater scope for spending.
The contrasting person has had their provision قُدِرَ عليه, restricted or narrowed.
Rendering saʿah through “wealth” is therefore natural in this context, but the root does not simply mean money. Wealth is one form of ample resources.
Al-Nisāʾ 4:100 says that a person who migrates will find مراغما كثيرا وسعة in the earth. Saʿah cannot confidently be restricted to wealth here; the broader sense of room, opportunity and relief from constriction fits more naturally.
Saʿah can thus concern space, circumstances, resources or wealth. Context identifies the kind of breadth involved.
“Wāsiʿ”: a description completed by context
The masculine form واسع describes The God nine times in the Qur’an. These occurrences do not use al-wāsiʿ with the definite article; they include forms such as والله واسع عليم and واسع المغفرة.
In many cases, wāsiʿ accompanies giving and bounty. For example:
وَإِنْ يَتَفَرَّقَا يُغْنِ اللَّهُ كُلًّا مِنْ سَعَتِهِ ۚ وَكَانَ اللَّهُ وَاسِعًا حَكِيمًا
“If the two separate, The God will enrich each from His abundance. The God is ample in bounty, wise.”
Al-Nisāʾ 4:130
The preceding clause already contains مِنْ سَعَتِهِ. Wāsiʿan is therefore clearly connected in this context with abundant resources, giving and making each person free of need.
Al-Baqarah 2:261 follows the multiplication of charitable spending with والله واسع عليم. In 2:268 the context is a promise of forgiveness and bounty; Āl ʿImrān 3:73 and al-Māʾidah 5:54 concern bounty; al-Nūr 24:32 concerns enriching the poor from His bounty.
In this group of verses, wāsiʿ should not simply become “infinitely large in space.” The root relates to ample giving, scope, knowledge and freedom from constriction.
Al-Najm 53:32 explicitly identifies the scope of the description: إِنَّ رَبَّكَ وَاسِعُ الْمَغْفِرَةِ, “Indeed, your Lord is vast in forgiveness.”
Wāsiʿ therefore has no single equivalent independent of context. “Abundant in giving,” “of ample scope” or, in some contexts, “encompassing” can each convey an aspect of its meaning.
“To The God belong the east and the west … The God is wāsiʿ, knowing”
Al-Baqarah states:
وَلِلَّهِ الْمَشْرِقُ وَالْمَغْرِبُ ۚ فَأَيْنَمَا تُوَلُّوا فَثَمَّ وَجْهُ اللَّهِ ۚ إِنَّ اللَّهَ وَاسِعٌ عَلِيمٌ
“To The God belong the east and the west. Wherever you turn, there is the face of The God. Indeed, The God is all-encompassing, knowing.”
Al-Baqarah 2:115
The placement of واسع after the east, the west and “wherever you turn” matters, but it should not be made to express more than the root supports.
Wāsiʿ here does not say that The God is an enormous body spatially filling every direction. The root does not require such a bodily image.
At the same time, the choice of wāsiʿ after opening the range from east and west to أينما, “wherever,” accords with the idea of breadth rather than confinement.
Further interpretation must draw on the Qur’anic uses of “face,” “east” and “west,” and the full context of 2:115, rather than on و س ع alone.
Wāsiʿ must be read with this sentence and the related verses; the word alone does not determine everything meant by “the face of The God.”
“Al-mūsiʿ”: someone of ample means
Al-Baqarah uses مُوسِع for a person’s financial means:
لَا جُنَاحَ عَلَيْكُمْ إِنْ طَلَّقْتُمُ النِّسَاءَ مَا لَمْ تَمَسُّوهُنَّ أَوْ تَفْرِضُوا لَهُنَّ فَرِيضَةً ۚ وَمَتِّعُوهُنَّ عَلَى الْمُوسِعِ قَدَرُهُ وَعَلَى الْمُقْتِرِ قَدَرُهُ مَتَاعًا بِالْمَعْرُوفِ حَقًّا عَلَى الْمُحْسِنِينَ
“There is no blame upon you if you divorce women before having relations with them or assigning them a prescribed due. Provide for them: the person of ample means according to their means, and the person of restricted means according to theirs—a fitting provision, a duty upon those who do good.”
Al-Baqarah 2:236
الموسع contrasts with المقتر.
Here mūsiʿ means someone possessing ample resources, rather than necessarily someone actively enlarging something at that moment.
This use matters for the verse in al-Dhāriyāt: the same morphological form can express possessing ample means or capacity.
“Wa-innā la-mūsiʿūn” alongside the other occurrence of mūsiʿ
Al-Dhāriyāt states:
وَالسَّمَاءَ بَنَيْنَاهَا بِأَيْدٍ وَإِنَّا لَمُوسِعُونَ
“And the heaven—We built it with strength, and indeed We possess vast capacity.”
Al-Dhāriyāt 51:47
In this sentence, بِأَيْدٍ accompanies the building of the heaven, while لَمُوسِعُونَ describes the speaker. “We possess vast capacity” is deliberately broad here, to avoid putting more specificity into the translation than the expression itself determines.
The other Qur’anic use of the same form helps clarify the description mūsiʿūn.
موسعون is the plural of mūsiʿ. In al-Baqarah 2:236, al-mūsiʿ contrasts with al-muqtir and designates a person with ample financial resources. There the contrast itself identifies the kind of abundance.
In al-Dhāriyāt 51:47 the subject is the building of the heaven. The financial meaning in al-Baqarah should therefore not simply be transferred to this verse. That occurrence does, however, show that the pattern mūsiʿ need not designate an act of spatial enlargement.
In وَإِنَّا لَمُوسِعُونَ, no object follows the description, and no expression such as “continually” explicitly specifies duration. A particular physical process or its temporal continuity cannot be established from this phrase alone.
Comparing these two Qur’anic occurrences supports the following conclusion:
Mūsiʿ is connected with ample scope and capacity. In al-Baqarah this concerns financial resources; in al-Dhāriyāt it is a description within a statement about building the heaven. The same morphological form does not make every semantic detail of the two contexts identical.
Wusʿ, saʿah and wāsiʿ: one family, three perspectives
Three principal forms can be distinguished without collapsing them into one:
Wusʿ chiefly expresses available capacity to bear or perform something. This is why it accompanies charging a person with a responsibility.
Saʿah is the condition of having ample room or scope, whether in place, wealth, life or resources.
Wāsiʿ describes something or someone with ample scope or capacity rather than constriction. The associated noun or context identifies the kind of breadth: the earth is spacious, mercy is encompassing, forgiveness is extensive, and The God is described as wāsiʿ in contexts of bounty and knowledge.
These are not three unrelated meanings. A shared question connects them:
Does the space, ability, range or resource have sufficient room and capacity for what it faces, or is it too restricted?
W S ʿ and Ḍ Y Q: breadth and constriction
The contrast between ample room and constriction can be examined within the Qur’an itself.
The earth is واسعة in al-ʿAnkabūt 29:56. Al-Tawbah 9:25 and 9:118 describe the earth becoming narrow despite its breadth: ضَاقَتْ عَلَيْكُمُ الْأَرْضُ بِمَا رَحُبَتْ and ضَاقَتْ عَلَيْهِمُ الْأَرْضُ بِمَا رَحُبَتْ. In these last two verses, the word expressing breadth belongs to ر ح ب. This is a comparison between contexts, not a direct pairing of W S ʿ and Ḍ Y Q in one sentence.
The contrast keeps the meaning of W S ʿ from becoming excessively abstract.
The underlying question is whether there is room or constriction, capacity or inability, ample resources or restriction.
This image helps connect the spatial, financial and human usages. With knowledge and mercy, the sentence itself identifies the domain of encompassing.
Wusʿ and ṭāqah: close, but not automatically identical
Al-Baqarah 2:286 uses wusʿ and ṭāqah in the same verse, showing that the Qur’an has two distinct words available.
Wusʿ belongs to the field of room and capacity: something fits within a person’s ability.
Ṭāqah concerns strength and endurance.
The verse alone does not establish a fixed quantitative relationship between wusʿ and ṭāqah.
Wusʿ here concerns a person’s capacity to carry out what they are charged with. The continuation also asks that people not be made to bear what they lack the strength to endure.
Translation choices
For spatial uses such as أرضي واسعة, “My earth is spacious” or “My earth is vast” is natural.
For وسع كرسيه السماوات والأرض, “His kursī encompasses the heavens and the earth” is more natural than “became wide over the heavens.” The explanation should make clear that the root itself does not determine what kursī denotes.
For وسع كل شيء علما, “He encompasses everything in knowledge” preserves the dimension stated by the verse. “Encompassing knowledge” is also possible in explanatory prose, without treating wasiʿa and aḥāṭa as identical roots.
For رحمة واسعة, “encompassing mercy” or “extensive mercy” is appropriate.
For لا يكلف الله نفسا إلا وسعها, “beyond its capacity” or “beyond its ability” preserves the sense better than “beyond what is easy.” Absolute ease is not contained in the word itself.
In ذو سعة من سعته, the financial context permits “Let someone of ample means spend from their abundance,” or more briefly, “Let the wealthy spend from their wealth.”
When wāsiʿ describes The God, no single equivalent works everywhere. “Abundant in giving,” “of ample scope,” “vast in bounty” and “encompassing” can be considered according to the sentence. Translation should not automatically turn the description into bodily size.
For إنا لموسعون, “Indeed We possess vast capacity” retains a connection with the root without settling every detail of the intended meaning. Adding an object such as “the heaven,” or an adverb such as “continually,” requires an argument beyond the description itself.
Conclusion
The Qur’anic uses of و س ع are connected by breadth, room and capacity.
In the poetry transmitted from al-Rabīʿ ibn Ziyād, saʿah accompanies breadth, length and room for departure. In al-Nābigha’s verse, tasaʿ contrasts with ḍāqa, using space to express a sense of ease or constriction.
In the Qur’an, the earth is واسعة, offering room to move and find another place. The kursī encompasses the heavens and the earth. Knowledge encompasses everything, and mercy can likewise embrace everything within its scope.
Wusʿ concerns human capacity and sets a limit to what a person is charged with. Al-Baqarah 2:286 also uses ṭāqah, but does not by itself establish a fixed numerical relationship between the two.
Saʿah is ample scope in circumstances and resources. Sometimes it is explicitly financial; sometimes it concerns a broader opening in life and place.
Wāsiʿ, including its feminine form, describes the earth and mercy; its masculine form also describes The God nine times. Contexts of bounty, enrichment, knowledge and forgiveness prevent reducing it to a purely spatial conception. The sentence identifies the relevant scope.
In al-Baqarah 2:115, wāsiʿ ʿalīm follows east, west and “wherever you turn.” This accords with breadth rather than confinement, but the root alone does not construct a complete account of “the face of The God” or of The God’s relation to space.
La-mūsiʿūn in al-Dhāriyāt 51:47 must be read within the statement about building the heaven. Al-mūsiʿ in al-Baqarah 2:236 shows that this form can express possession of ample resources. The morphological form alone does not settle the details of a spatial process or its continuation through time.
W S ʿ: breadth, room and capacity. Qur’anic usages include spatial extent, human ability, ample resources and wealth, and encompassing through knowledge and mercy. Context identifies the kind and scope of breadth involved; this family does not invariably mean bodily extent, infinity or absolute ease.
