Mukhtasar Bukhari

Narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet Muhammad (peace and blessings be upon him) in Madinah would not visit anyone’s house except that of Umm Sulaym and his noble wives. So someone asked the Prophet (peace and blessings be upon him) the reason for this, and he (peace and blessings be upon him) replied: “I feel compassion for her; her brother was martyred along with me.”
