Volume 3, Book 48, Number 812:
Narrated Aisha:
Aflah asked the permission to visit me but I did not allow him. He said, “Do you veil yourself be –
fore me although I am your uncle?” ‘Aisha said, “How is that?” Aflah replied, “You were suckled by
my brother’s wife with my brother’s milk.” I asked Allah’s Apostle about it, and he said, “Allah is right,
so permit him to visit you.”
