Muhammad said: ‘A’ishah came to Safiyyah Umm Talha al-Talhat and seeing her daughter she said: The Messenger of Allah (ﷺ) entered (into the house) and there was a girl in my apartment. He gave his lower garment (wrapper) to me and said; tear it into two pieces and give one-half to this (girl) and the other half to the girl with Umm Salamah. I think she has reached puberty, or (he said) I think they have reached puberty. Abu Dawud said: Hisham has narrated it similarly from Muhammad b. Sirin.
