Qatadah (may Allah have mercy on him) said concerning the verse "It is not for a believing man or a believing woman, when Allah and His Messenger have decided a matter, that they should have any choice in their affair; and whoever disobeys Allah and His Messenger has certainly strayed into clear error" [al-Ahzab: 36]: This verse was revealed concerning Zaynab bint Jahsh (may Allah be pleased with her), and she was the daughter of the paternal aunt of the Messenger of Allah (peace and blessings be upon him). The Messenger of Allah (peace and blessings be upon him) proposed to her, and she was pleased, thinking that he (peace and blessings be upon him) was proposing for himself. But when she learned that he (peace and blessings be upon him) was proposing on behalf of Zayd bin Harithah (may Allah be pleased with him), she refused and disapproved. So Allah revealed: "It is not for a believing man or a believing woman, when Allah and His Messenger have decided a matter, that they should have any choice in their affair; and whoever disobeys Allah and His Messenger has certainly strayed into clear error."
