Sayyiduna Anas bin Malik (may Allah be pleased with him) said: I entered the house of Sayyiduna Abu Talhah (may Allah be pleased with him). He had shut the door on Sayyidah Umm Sulaym (may Allah be pleased with her) - who was Anas's mother - and was beating her. So I called out from behind the door: Why are you beating this old woman? My mother then called out to me from behind the door and said: You call me "old woman"? May Allah weaken your arm.
