Hasan al-Hulwani narrated to us, saying: 'Amr ibn 'Asim narrated to us, saying: Hammam narrated to us, from Ishaq ibn 'Abdullah, from Anas, who said: The Prophet, peace and blessings be upon him, would not enter upon any of the women except his wives, with the exception of Umm Sulaym, for he would enter upon her. It was said to him regarding that, and he said: "I have compassion for her, for her brother was killed alongside me."
