Ayesha reported,

Aisha said, "My uncle through breastfeeding came asking permission to visit me, and I refused to allow him in until I could consult the Messenger of Allah ﷺ. When the Messenger of Allah ﷺ came, I said, 'My uncle through breastfeeding asked permission to visit me, and I refused to let him in.'The Messenger of Allah ﷺ said, "Let your uncle come in to you."I said, "It was the woman who nursed me, not the man."He said, "He is indeed your uncle, so let him come in to you."
