Is it true that Imam Abu Hanifa and Imam Malik said that the husband is not obligated to fulfill a permissible condition stipulated by the wife in the marriage contract, even if he agreed to it, such as the condition that he allow her to work or study, and does this mean that it is permissible for a man to deceive a woman in this regard?

In summary:

Scholars have differed on the ruling regarding conditions in a marriage contract, and whether fulfilling them is obligatory or recommended.

Some jurists are of the opinion that these conditions are not binding, because a wife's time is for her husband and her home, and her going out for work or study contradicts the essence of the marriage contract.

The website favors the view that it is obligatory to fulfill conditions stipulated by the woman for her benefit, as long as they do not contradict Islamic law or the purpose of the contract, such as stipulating the right to study or work, or that he shall not marry another wife. This is based on the general evidence that commands fulfilling contracts, such as Allah’s saying: (O YOU WHO HAVE BELIEVED, FULFILL [YOUR] CONTRACTS), and the Prophet's (peace be upon him) saying: (The conditions most worthy of fulfillment are those by which you make intimacy lawful.) This is the view of the Hanbalis and some Malikis, and the choice of Ibn Taymiyyah, Ibn al-Qayyim, and Ibn 'Uthaymeen.

Nevertheless, the other opinion, which states that these conditions are not binding, is a valid view, and two narrations concerning it have been reported from Umar ibn al-Khattab (may Allah be pleased with him).
