Muwatta Imam Malik Book of General Subjects, Hadith 1

Malik related to me from Safwan ibn Sulaym from Ata ibn Yasar that the Messenger of Allah ﷺ was questioned by a man who said, "Messenger of Allah, shall I ask permission of my mother to enter?" He said, "Yes " The man said, "I live with her in the house". The Messenger of Allah ﷺ said "Ask her permission." The man said, "I am her servant." The Messenger of Allah. may Allah bless him and grant him peace, said, "Ask her permission. Do you want to see her naked?" He said, "No." He said, "Then ask her permission."
