Bayhaqi 15473 — The waiting period of a pregnant widow

It is narrated from Muhammad bin Sirin (may Allah have mercy on him) that he said: I was sitting with Abd al-Rahman bin Abi Layla (may Allah have mercy on him), and his companions were honouring him as though he were their leader. They mentioned the later of the two terms, and I mentioned the hadith of Abdullah bin Utbah (may Allah be pleased with him) about Subay'ah bint al-Harith (may Allah be pleased with her). Ibn Sirin (may Allah have mercy on him) said: One of his companions winked at me, and I understood, and I said: I am not eager to lie; if I were to lie about Abdullah bin Utbah (may Allah be pleased with him), Abdullah bin Utbah (may Allah be pleased with him) is right there on the outskirts of Kufah. Ibn Sirin (may Allah have mercy on him) said: He felt somewhat ashamed and said: But his uncle did not say that. Ibn Sirin (may Allah have mercy on him) said: And I had not heard anything about it from Abdullah (may Allah be pleased with him). So I got up and met Abu Atiyyah Malik bin al-Harith (may Allah have mercy on him) and asked him, and he began narrating to me the hadith of Subay'ah (may Allah be pleased with her). I said: I am not asking you about this; have you heard anything about it from Abdullah (may Allah be pleased with him)? He said: Yes. We were with Abdullah (may Allah be pleased with him) and asked him about her, and he said: What do you think if she gives birth before four months and ten days? We said: (She waits) until they pass. He said: What do you think if four months and ten days pass before she gives birth? We said: Until she gives birth. Abdullah (may Allah be pleased with him) said: You impose hardship on her and do not grant her the concession! The shorter Surah al-Nisa was revealed after the longer one: 'And for those who are pregnant, their term is until they deliver their burden.' [Surah al-Talaq: 4]
Al-Bukhari (may Allah have mercy on him) recorded it.
