Qur'anic Root Q D S

Foundational Meaning

The root Q D S is fundamentally connected with purity and a pure boundary. It does not point only to outward cleanliness; it points to a kind of purity that separates and protects a sanctified domain. Something is kept apart from contamination, deficiency, impurity, or ordinary access.

From this come meanings such as taqdis, quddus, ruh al-qudus, and sacred land. In all these uses, purity is not merely a surface condition; it is a purity that creates boundary and keeps false attribution or contamination away.

Important Forms

The Form II verb of this root is قَدَّسَ (qaddasa): to regard as pure, to purify, or to set a domain apart from contamination. In the Qur'an, the form نُقَدِّسُ (nuqaddisu) appears.

Qudus appears as a noun in the phrase رُوحِ الْقُدُسِ (rūḥ al-qudus). This phrase is one of the most important uses of this root in the Qur'an and should be studied carefully in its own article. In this entry, only its lexical field is noted: a spirit related to purity, sacred boundary, and divine strengthening.

قُدُّوس (quddūs) is an attribute used in the Qur'an concerning The God. It indicates absolute purity, sacred set-apartness, and freedom from every contamination and deficiency. مُقَدَّس (muqaddas) is a passive participle: purified, sanctified, having a pure boundary, or set apart from contamination. Its feminine form is مُقَدَّسَة (muqaddasah).

Linguistic Note

The semantic core of Q D S is purity together with boundary. Not every kind of purity in Arabic is necessarily qudus. Q D S points to purity that contains separation, sanctity, and boundary. Something sacred is not merely clean; it is separated from contamination, violation, and ordinary consumption.

For this reason, Q D S is very close to the idea of sacred boundary. A boundary is a domain into which every kind of entry, possession, or attribution is not permitted. When The God is called al-Quddūs, the meaning is not only that He is pure; His rank is set apart from every deficiency, contamination, limiting resemblance, partner, injustice, need, and false attribution.

Material Image

The material image of this root can be understood through washing, purifying, separating, and placing a boundary. It is as if something is drawn out of contamination and placed in a station that must not be polluted.

If the root S B Ḥ carried the image of remaining afloat and moving away from sinking, Q D S carries the image of established purity with sacred boundary.

In earthly uses, muqaddas is used about a place that has a pure boundary and special sanctity. Such a place is not merely an ordinary piece of land; in religious language, it is recognized as separated from contamination and violation. In divine use, Quddūs shows the absolute purity and sacred set-apartness of The God.

Older Arabic Usage

In older Arabic, this root was connected with purity, blessing, purification, and sacred boundary. Words such as qudus and muqaddas were used in the field of purity and sanctity. Lexical sources often connect this root with purity, purification, and sanctification, and the same field appears in the Qur'an.

If a reliable witness from pre-Islamic poetry or older Arabic usage is found for qudus and muqaddas, it can be added here. If a specific lexical use such as the name of a vessel or washing tool is confirmed in reliable sources, it may also be added as a material witness for the root. Until there is a precise witness, it is better to avoid specific claims about pre-Islamic poetry or ancient tools and remain with the general lexical field.

Nuqaddisu Laka

The first important use is the pairing of nusabbiḥu and nuqaddisu in the speech of the angels:

وَنَحْنُ نُسَبِّحُ بِحَمْدِكَ وَنُقَدِّسُ لَكَ (wa-naḥnu nusabbiḥu bi-ḥamdika wa-nuqaddisu laka)

And we make tasbih with Your praise, and we sanctify for You.

Al-Baqarah 2:30

This verse is important for the difference between S B Ḥ and Q D S. Nusabbiḥu bi-ḥamdika shows transcendence together with praise. Nuqaddisu laka conveys regarding as pure, preserving sacred boundary, and attributing purity to the rank of The God. The two are close, but not identical. Tasbih is more about declaring distance from deficiency and false attribution; taqdis is more about holding as pure and affirming a pure boundary for The God.

The structure نُقَدِّسُ لَكَ (nuqaddisu laka) is also important. The phrase does not say nuqaddisuka; it says nuqaddisu laka. The letter lām shows direction and dedication: sanctification is for The God, in relation to The God, and the pure domain is preserved for Him.

Ruh Al-Qudus

The second use is رُوحِ الْقُدُسِ (rūḥ al-qudus):

وَأَيَّدْنَاهُ بِرُوحِ الْقُدُسِ (wa-ayyadnāhu bi-rūḥi al-qudus)

And We strengthened him with ruh al-qudus.

Al-Baqarah 2:87

وَأَيَّدْنَاكَ بِرُوحِ الْقُدُسِ (wa-ayyadnāka bi-rūḥi al-qudus)

And We strengthened you with ruh al-qudus.

Al-Ma'idah 5:110

In this phrase, qudus is connected with purity and sacred boundary. Rūḥ al-qudus should not be identified in this entry with one definitive interpretive referent. The phrase needs an independent article on rūḥ, qudus, and its Qur'anic uses. Here we only say that qudus places the spirit in relation to purity and divine strengthening.

Another use appears in An-Nahl:

قُلْ نَزَّلَهُ رُوحُ الْقُدُسِ مِن رَّبِّكَ بِالْحَقِّ (qul nazzalahu rūḥu al-qudusi min rabbika bi-al-ḥaqq)

Say: ruh al-qudus has brought it down from your Lord with the truth.

An-Nahl 16:102

Here too, rūḥ al-qudus is connected with the descent of truth. For analysis of the root Q D S, the main point is that qudus in the phrase shows the pure and sacred field of this spirit, not that it alone determines the referent of the spirit.

Al-Quddus

The third field is the name الْقُدُّوس (al-quddūs) concerning The God:

الْمَلِكُ الْقُدُّوسُ (al-maliku al-quddūs)

The King, The Quddus.

Al-Hashr 59:23

الْمَلِكِ الْقُدُّوسِ (al-maliki al-quddūs)

The King, The Quddus.

Al-Jumu'ah 62:1

Quddūs is a strong attribute for absolute purity and sacred set-apartness. It may be rendered as the absolutely pure, the one pure and set apart from every deficiency, or the transcendent and pure. But Quddūs is not exactly the same as Subḥān. Subḥān is a structure of declaring transcendence; Quddūs is an attribute and name that shows absolute purity and sacred boundary.

The Sacred Valley

The fourth field is sacred place:

إِنَّكَ بِالْوَادِ الْمُقَدَّسِ طُوًى (innaka bi-al-wādi al-muqaddasi ṭuwā)

You are in the sacred valley of Tuwa.

Ta-Ha 20:12

In the same context:

فَاخْلَعْ نَعْلَيْكَ (fa-ikhla' na'layka)

So remove your sandals.

Ta-Ha 20:12

Here muqaddas describes the valley. For root analysis, the point is that the place is separated from ordinary status by the description muqaddas and receives a pure boundary. Removing the sandals also appears in the same context of the place's boundary and purity.

The Sacred Land

Another use appears in the expression sacred land:

يَا قَوْمِ ادْخُلُوا الْأَرْضَ الْمُقَدَّسَةَ (yā qawmi udkhulū al-arḍa al-muqaddasah)

O my people, enter the sacred land.

Al-Ma'idah 5:21

Here muqaddasah describes the land. Its basic meaning is land known by purity, sanctity, and special standing. This use should not be carelessly turned into political ownership or ethnic superiority. The word itself shows special sacred purity and boundary, not all later historical and political claims.

Distinguishing Similar Uses

Nuqaddisu laka in Al-Baqarah 2:30 refers to an act of taqdis in relation to The God: regarding as pure and preserving sacred boundary for the rank of The God.

Rūḥ al-qudus is a special phrase that should be studied separately. In this entry, only the role of qudus is clarified: purity and sacred boundary.

Al-Quddūs is an attribute of The God and points to absolute purity and sacred set-apartness.

Al-wādi al-muqaddas and al-arḍ al-muqaddasah are places separated by the description of purity and sanctity.

Structural Notes

In نُقَدِّسُ لَكَ (nuqaddisu laka), the letter lām is important. Taqdis is for The God; that is, the direction and end of taqdis is The God. The angels do not say nuqaddisuka in this expression, but nuqaddisu laka. This structure can be understood as preserving a pure domain for The God, or practicing purity in relation to Him.

In رُوحِ الْقُدُسِ (rūḥ al-qudus), the phrase is an iḍāfah construction. Qudus is the second term and connects the spirit to the field of purity and sacred boundary. This phrase should not be limited to one historical or interpretive referent without separate study.

In الْوَادِ الْمُقَدَّسِ (al-wādi al-muqaddas) and الْأَرْضَ الْمُقَدَّسَةَ (al-arḍa al-muqaddasah), muqaddas and muqaddasah are passive participles: purified, sanctified, or marked by purity and sanctity. The description creates a linguistic boundary around the place.

Nearby Roots

Q D S is close to S B Ḥ, but they are not the same. Sabḥ points to declaring distance from deficiency and false attribution, and its root image is floating movement and remaining away from falling. Q D S focuses on purity, sacred boundary, and separation from contamination. Tasbih is more the movement of language and understanding in transcendence; taqdis is more preserving a pure domain and sacred boundary.

Q D S also differs from Ṭ H R. Ṭuhr is purity from contamination, dirt, impurity, or a blocking state; it can be used for body, clothing, house, women, and practical purification. Q D S is bounded and separated purity, a purity joined with sanctity and special standing. Everything sacred is pure, but not every purity is necessarily sacred.

Q D S is not the same as Z K W. Zakā is connected with pure growth, flourishing, tazkiyah, and clean increase. Q D S is connected with a pure boundary and separation from contamination. Tazkiyah can be a process of growth and purification; taqdis is more the establishment of sanctity and purity of a domain.

Q D S also differs from Ḥ R M. Ḥaram points to prohibition, sanctity, and the forbidding of entry or possession. Q D S points to purity and pure boundary. The two can come close, because a sacred domain often has restriction; but ḥaram emphasizes prohibition and practical boundary, while qudus emphasizes purity and sanctity.

Q D S is close to N Z H in the sense of transcendence, but nazaha more directly points to being distant and removed from flaw or contamination, while Q D S highlights pure boundary and the rank of sanctity.

Translation Suggestions for Forqan

For نُقَدِّسُ لَكَ (nuqaddisu laka), suggested renderings are we sanctify for You, we preserve the pure domain for You, or we maintain sacred purity in relation to You. Depending on context, sanctify can be retained, but the meaning of purity and boundary should be explained.

For رُوحِ الْقُدُسِ (rūḥ al-qudus), suggested renderings are the pure spirit, the sacred spirit, or the spirit related to the pure domain. Since this phrase needs an independent article, the main translation may keep rūḥ al-qudus and explain it as a spirit related to divine purity and sacred boundary.

For الْقُدُّوس (al-quddūs), suggested renderings are Quddus, the absolutely pure, the one pure and set apart from every deficiency, or the transcendent and pure. If the translation keeps the Qur'anic word, Quddus is suitable, but the meaning should be opened in explanation.

For الْوَادِ الْمُقَدَّسِ (al-wādi al-muqaddas), suggested renderings are the sacred valley, the pure and sanctified valley, or the purified valley.

For الْأَرْضَ الْمُقَدَّسَةَ (al-arḍa al-muqaddasah), suggested renderings are the sacred land, the pure and sanctified land, or the purified land.

Summary

The root Q D S indicates purity, purification, sacred boundary, and separating a pure domain from contamination. At the material level, its image is washing, purifying, separating, and placing a boundary. In the Qur'an, this root is used for sanctifying for The God, rūḥ al-qudus, the name al-Quddūs, and sacred places.

Its difference from S B Ḥ is that tasbih more strongly means declaring The God far from deficiency and false attribution, while taqdis more strongly shows purity and sacred boundary. Its difference from Ṭ H R is that ṭaharah is purity from contamination, while qudus is purity joined with sanctity and separation of domain.
