Musannaf Ibn Abi Shaybah

Hasan (may Allah have mercy on him) used to say that a woman who has been given three divorces and is pregnant, and a woman who has been subjected to ila’ and is pregnant, then maintenance (nafaqah) will be obligatory for her.

Ibrahim (may Allah have mercy on him) said that a woman who has been given three divorces, or has been subjected to ila’, or has taken khul‘, or has undergone li‘an, if all of them are pregnant, then their maintenance is obligatory upon the husband. However, if the woman who has taken khul‘ has agreed not to take maintenance, then maintenance is not obligatory.
