Sunan an-Nasa'i 3512

Qutaybah informed us; he said: al-Layth narrated to us, from Yahya, from Sulayman ibn Yasar, that Abu Hurayrah, Ibn Abbas, and Abu Salamah ibn Abd al-Rahman discussed the waiting period of a woman whose husband died while she was pregnant and who gave birth after his death. Ibn Abbas said, ‘She must observe the later of the two terms.’ Abu Salamah said, ‘Rather, she becomes permitted to marry as soon as she gives birth.’ Abu Hurayrah said, ‘I side with my brother’s son.’ They sent to Umm Salamah, the wife of the Prophet, and she said, ‘Subay'ah al-Aslamiyyah gave birth shortly after her husband died. She sought a ruling from the Messenger of Allah, and he instructed her to marry.’
