His father reported that the Prophet ﷺ said to Asim bin Adi, "Keep the woman with you until she gives birth."
عن أبيه، أن النبي ﷺ قال لعاصم بن عدي: أمسك المرأة عندك حتى تلد.
Abu Dawud (2246) narrated it from Abdul-Aziz bin Yahya, who said, "Muhammad (meaning Ibn Salama) narrated to us, from Muhammad bin Ishaq, who said, 'Abbas bin Sahl narrated to me, from his father,'" and he mentioned it. Its isnad is hasan because of Muhammad bin Ishaq, except that he alone reported the phrase, "Keep the woman with you until she gives birth," even though this story has been narrated through many routes, none of which contain "Keep the woman with you until she gives birth."Imam Ahmad (22837) narrated it through the route of Ibn Ishaq, and he added, "If she gives birth to him reddish, then he belongs to his father, the one who disowned him, that is, to Uwaymir, but if she gives birth to him with tightly curled hair and a black tongue, then he belongs to Ibn Sahma." Asim said, "When he was born, I took him to myself, and I found his head like the fleece of a small lamb. Then I took him," Yaqub said, "by his jaws, and he was reddish like a nab'ah branch, and his tongue faced me, black like a date." He said, "So I said, 'Allah and His Messenger have spoken the truth.'"His saying "tightly curled hair" means intensely coiled, like the hair of black people. His saying "by his jaws" means by his two jawbones.As for his saying, "Keep the woman until she gives birth," Shafii held onto it as evidence, saying, "She has housing but no maintenance," and this is also the view of Zuhri and Malik. Abu Hanifa and his companion Muhammad bin Hasan Shaybani said, "She has both maintenance and housing, because liaan is an irrevocable divorce." Ahmad, Abu Thawr, Abu Ubayd, and others said, "She has neither maintenance nor housing." Athram related from Ahmad that he said, "This is more severe than a woman divorced three times," meaning she has neither maintenance nor housing. Ibn Munzir mentioned this in Awsat (526/9).The sound conclusion on this matter is that if the liaan concerned the pregnancy itself, then she has neither maintenance nor housing, but if the liaan concerned something other than the pregnancy, then the pregnant woman is entitled to both maintenance and housing, because the child belongs to him, so he must provide for it, which makes her like a pregnant woman who has been irrevocably divorced.
