Those are the ones who purchased misguidance with guidance; so their trade did not profit, and they were not guided.
This verse is the result and summary of the path that began in verse 8. The Qur’an spoke of people who claimed faith while they were not believers; imagined they were deceiving the One God and the believers while deception returned to themselves; carried disease in their hearts; called corruption reform; called the believers foolish; returned in privacy toward their devils; and made faith an object of mockery. Now verse 16 explains that whole path through the language of trade: they took something and paid something in exchange.
The key word is ishtaraw. It opens the field of buying, selling, exchange, and replacing one thing with another. The Qur’an is not saying that the One God needs to trade with human beings. He is the Rich and Praiseworthy; human profit or loss adds nothing to Him and removes nothing from Him. But the human being is a creature who, through choices, trades. Every decision contains a taking and a leaving.
A human being usually acts after weighing value and outcome. Before many decisions, a person calculates inwardly: if I take this road, what will I gain? What will I lose? Which outcome is nearer, easier, safer, more useful, or more desirable? Then, based on that weighing, one path is chosen. With the language of ishtaraw, the Qur’an shows this truth: life is a field of choices, and every choice has a price.
The verse says: ishtaraw aḍ-ḍalālata bil-hudā — they purchased misguidance with guidance. This expression is precise. In the structure of the verse, guidance is what was paid in exchange for taking misguidance. They spent the capital of guidance in order to acquire misguidance. Guidance was before them: the possibility of truthfulness, faith, reform, return, and finding the way. But they let that capital go and chose misguidance in its place.
Their misguidance, then, was not simple lack of knowledge. Someone who has never seen a path is not the same as someone who sees the path and spends it on a roadless way. They encountered guidance, but in their calculation they preferred what was nearer and more worldly: outward safety, social position, short-term benefit, influence, companionship with circles of power, or the false comfort of privacy with their devils.
Their loss begins here. They imagined that this two-facedness would bring profit: among the believers they would keep the face of faith, and in privacy with their devils they would also preserve their place. They imagined they could benefit from the language of faith while remaining secretly loyal to the side opposed to truth. But the Qur’an says: fa-mā rabiḥat tijāratuhum — their trade did not profit.
This statement is not only about the Hereafter, though it includes the Hereafter. First, this trade itself fails in this life. Whoever lives by deception loses the peace of truthfulness. Whoever moves between two faces lacks inward stability. Whoever exchanges guidance for misguidance may appear to have movement, plans, influence, or success, but in reality remains in the wandering of the previous verse: yaʿmahūn. There is movement, but no direction; calculation, but no true profit.
“Their trade did not profit” means their calculation was wrong from its foundation. They imagined as profit things that move a person away from guidance. In the Qur’an, not every benefit is profit. If a person gains something worldly through a choice but loses truthfulness, peace, trustworthiness, guidance, and the possibility of a good Hereafter, the transaction is truly loss. Real profit is what brings a human being nearer to truth, not what makes them look successful for a few days while making their inward life more directionless.
The Hereafter is not separate from the verse. Guidance in the Qur’an is not only for arranging a few days of worldly life. It is a path that leads the human being toward salvation, right accounting, and a more lasting life. Through their choices, the hypocrites took the near result of the world, but deprived themselves of the greater possibilities of the Hereafter. They preferred a few days of apparent benefit or safety over a path that could have led them to a good end.
Opposite this losing trade, the Qur’an elsewhere speaks of a saving trade: faith in the One God and His messenger, and striving in the path of truth with wealth and self. That trade saves a human being from painful punishment. So the Qur’an does not reject the language of trade; it corrects the measure of profit. Profitable trade is what brings a person closer to guidance, salvation, and divine pleasure. Losing trade is when a person spends guidance on misguidance.
The verse ends: wa-mā kānū muhtadīn — and they were not guided. This is not merely a repetition of their failed trade. In the previous verse, the Qur’an said yaʿmahūn: they wander blindly. There, their movement and bewilderment were shown. Here, through mā kānū muhtadīn, it becomes clear that the description of being guided did not belong to them. Their repeated choices had formed an inward direction, and that direction was not compatible with guidance.
This verse warns us that hypocrisy is not only a problem of language or appearance. It is a problem of valuation. The hypocrite weighs things upside down: seeing the world as greater than the Hereafter, appearance as more important than reality, temporary safety as better than lasting truthfulness. He imagines companionship with his devils to be profit, but does not see that through that very choice he loses the capital of guidance.
Verse 16 clarifies the law of human choice: every decision is a transaction. A human being either moves through decisions toward guidance, truthfulness, and salvation, or through those same decisions purchases misguidance with guidance. Any trade that moves a human being away from truth, even if it appears profitable outwardly, has not profited in the Qur’an’s measure.
