What is the religious ruling on a wife's request to retract an agreement made before and during the engagement and after 7 years of marriage, which stipulates her contribution from her salary to household expenses, and then her request to retract a subsequent agreement made by mutual consent two years ago, which stipulates that she receives a monthly allowance and that you bear all her other expenses?

If the agreement to give the wife her salary was merely a promise, then fulfilling it is recommended (mustahabb) but not obligatory (wajib (definition)) according to the majority of jurists. However, if it was a condition, then the condition is invalid, but the contract remains valid, because it contradicts the essence of the contract.

The wife is not obliged to fulfill this condition, and she has the right to withdraw from it, because it is based on falsehood.

Furthermore, a husband exploiting his wife and taking her salary contradicts the good companionship (al-mu'ashara bil-ma'ruf) enjoined by the Sharia (definition). The husband is not permitted to take anything from his wife's money except with her willing consent, based on the Almighty's saying: "But if they give up willingly to you anything of it, consume it in satisfaction and ease." And the Prophet (peace be upon him) said: "The wealth of a person is not lawful except with his willing consent."
