Musnad Ahmad 1153:45

'Abd al-A'la narrated to us, from Ma'mar, from al-Zuhri, from 'Urwah ibn al-Zubayr, from 'A'ishah, that Aflah, the brother of Abu Qu'ays, sought permission to enter upon 'A'ishah, but she refused to grant him permission. When the Prophet (peace be upon him) came, she said: "O Messenger of Allah, Aflah, the brother of Abu Qu'ays, sought permission to enter upon me, and I refused to grant him permission." He said: "Grant him permission." She said: "O Messenger of Allah, it was the woman who nursed me, not the man." He said: "Grant him permission, for he is your paternal uncle; may your right hand be covered in dust."
