Bulugh al-Maram #1316

Narrated : Aflah (her foster suckling uncle), brother of Abul-Qais, came and asked her permission to enter after the Hijab (was instituted for women). She said, "I refused to allow him in and when Allah's Messenger (ﷺ) came, I told him about what I had done, so he commanded me to give him permission to enter where I am and said, 'He is your paternal uncle.'" .
