Musannaf Ibn Abi Shaybah

Hazrat Abdur Rahman bin Aflah narrates that he married the Umm-e-Walad slave woman of Hazrat Abu Ayyub (may Allah be pleased with him). She told him that Hazrat Abu Ayyub used to practice coitus interruptus (azl). And the Umm-e-Walad slave woman of Hazrat Zaid bin Thabit also told me that he too used to practice azl. Hazrat Salim narrates from Aisha (may Allah be pleased with her), daughter of Saad, that Hazrat Saad used to practice azl with his Umm-e-Walad slave women.
