Malik related to me from Safwan ibn Sulaym from Ata ibn Yasar
that the Messenger of Allah, may Allah bless him and grant him peace,
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, may Allah bless
him and grant him peace, 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."
Muwatta Malik Book 54, Hadith 1
Yahya related to me from Malik from Damra ibn Said al-Mazini from
al-Hajjaj ibn Amr ibn Ghaziya that he was sitting with Zayd ibn Thabit
when Ibn Fahd came to him. He was from the Yemen. He said, "Abu Said!
I have slave-girls. None of the wives in my keep are more pleasing to
me than them, and not all of them please me so much that I want a
child by them, shall I then practise coitus interruptus?" Zayd ibn
Thabit said, "Give an opinion, Hajjaj!" "I said, 'May Allah forgive
you! We sit with you in order to learn from you!' He said, 'Give an
opinion! 'I said, 'She is your field, if you wish, water it, and if
you wish, leave it thirsty. I heard that from Zayd.' Zayd said, 'He
has spoken the truth.' "
