Sahih al-Bukhari 4851

It is related from al-Miswar ibn Makhrama that Subay'a al-Aslamiyya gave birth some days after the death of her husband, and she went to the Prophet, may Allah bless him and grant him peace, and asked his permission to marry and he gave her permission and so she got married. XXXVIII. The words of Allah Almighty, "Divorced women should wait by themselves for three menstrual cycles." (2:228) Ibrahim [an-Nakha'i] said about a woman who married during the 'idda and had three periods while with him, that she is divorced from the first and there is no reckoning for the one after him [because the second marriage is invalid]. Az-Zuhri said that there is reckoning. This is what Sufyan preferred, i.e the verdict of az-Zuhri. Ma'mar said, "It was asked, 'Is it a qar' (monthly period) when her menstruation comes or when her purity comes?' It is said that there is no qar' by the membrane [of the foetus) alone and when is no child in her womb." [This means that qar' are only calculated by menstrual periods and periods of purity.] XXXIX. The story of Fatima bint Qays The words of Allah, "And show fear of Allah, your Lord. Do not evict them from their homes, nor should they leave, unless they commit an outright indecency. Those are Allah's limits, and anyone who oversteps Allah's limits has wronged himself. You never know, it may be that after that, Allah will cause a new situation to develop." (65:1) "Let them live where you live, according to your means. Do not put pressure on them, so as to harass them. If they are pregnant, maintain them until they give birth. If they are suckling for you, give them their wages and consult together with correctness and courtesy. But if you make things difficult for one another, another woman should do the suckling for you. He who has plenty should spend out from his plenty. But he whose provision is restricted should spend from what Allah has given him. Allah does not charge any self with more than He has given it. Allah will appoint after difficulty, ease." (65:6-7)
