What is the ruling on a woman prohibiting herself from marrying a specific man, then marrying another man, and is there any expiation required of her after her marriage and childbirth?

Scholars have differed regarding one who forbids something lawful for himself, other than his wife; does an expiation for an oath (kaffarat yamin) become obligatory upon him or not? The majority of scholars hold that expiation is not obligatory, citing as evidence the Almighty’s saying: "O you who have believed, do not prohibit the good things which Allah has made lawful for you." (Quran 5:87). Whereas the Hanafis and Hanbalis hold that expiation is obligatory, citing as evidence the Almighty’s saying: "O Prophet, why do you prohibit what Allah has made lawful for you…? Allah has already ordained for you the dissolution of your oaths." (Quran 66:1-2). The most preponderant view is that of the majority, because the noble verse was revealed in a story about which exegetes differed, with most of them believing that the Prophet (peace be upon him) first prohibited something and then took an oath.
