My maternal uncle Abu Burda b. Niyar passed me carrying a standard, and I asked him where he was going. He replied, “The Prophet has sent me to bring him the head of a man who has married his father’s wife.”
A version by Abu Dawud, Nasa’i, Ibn Majah and Darimi has, “He has ordered me to cut off his head and take his property.” This version has “my paternal uncle” instead of “my maternal uncle.”
Abu Huraira said that God’s Messenger forbade that a woman should be married to one who had married her paternal aunt, or a paternal aunt to one who had married her brother’s daughter, or a woman to one who had married her maternal aunt, or a maternal aunt to one who had married her sister's daughter. A younger sister must not be married to one who has married an elder sister, nor an elder sister to one who has married a younger sister.
Tirmidhi, Abu Dawud, Darimi and Nasa’i transmitted it, Nasa’i’s version ending with “her sister’s daughter.”
Umm Salama reported God’s Messenger as saying, “The only suckling which makes marriage unlawful is that which is taken from, the breast and enters the bowels, and is taken before the time of weaning.”
At the battle of Hunain God’s Messenger sent an army to Autas, and they met an enemy and fought with them. . Having prevailed over them and taken captives the Prophet’s companions seemed to hold back from having intercourse with them because of their husbands among the polytheists. Then God most high sent down regarding that, “And women already married, except those whom your right hands possess” (Al-Qur’an 4:24). That means that they were lawful for them when their ‘idda* period came to an end.
* The period which a widow or divorced woman must observe before remarriage. See Ch. 26.
