Musannaf Ibn Abi Shaybah 17398 — Coitus interruptus (azl)

Sayyiduna Jabir (may Allah be pleased with him) said: We used to practise 'azl while the Qur'an was being revealed, that is, no prohibition of it came. ('Azl means withdrawing from the private part during intercourse at the time of ejaculation and ejaculating outside.)
