Is it permissible for the wife to request a one-year postponement of wearing the niqab after marriage, given that the husband insists on her wearing it immediately, and is it permissible to write this condition into the marriage contract?

Covering a woman's face is obligatory according to the more preponderant opinions of jurists, and it is not permissible to neglect it. The suitor may stipulate this in the marriage contract, and if she agrees, she must adhere to it. If the woman is convinced of the obligation of the niqab for her, then she must adhere to it. If she is not convinced of its obligation, then the suitor has no right to compel her to wear it, unless he stipulates it and she agrees to it.
