Musannaf Ibn Abi Shaybah

Hazrat Muhammad bin Amr (may Allah have mercy on him) states that Hazrat Zuhri (may Allah have mercy on him) came to Madinah Munawwarah in the early days of Hisham’s caliphate and narrated that Hazrat Urwah (may Allah have mercy on him) relates from Hazrat Aisha (may Allah be pleased with her) that Abu Qais (may Allah have mercy on him) sought permission to meet Hazrat Aisha (may Allah be pleased with her). Hazrat Aisha (may Allah be pleased with her) and Abu Qais had both been breastfed by the wife of Abu Qais’s brother. Hazrat Aisha (may Allah be pleased with her) refused to grant him permission. Hazrat Urwah (may Allah have mercy on him) believes that Hazrat Aisha (may Allah be pleased with her) mentioned this to the Prophet ﷺ, so he said: Why did you not grant him permission? Breastfeeding makes unlawful what blood relations make unlawful. Upon hearing this statement of the Prophet ﷺ, the people of Madinah became anxious. Abdullah bin Abi Habibah, the freed slave of Zubair, divorced his wife on this occasion.
