Abu Bakr ibn Abi Shaybah and Ishaq ibn Ibrahim narrated to us. Ishaq said: informed us, and Abu Bakr said: narrated to us Sufyan, from 'Amr, from 'Ata', from Jabir, who said: We used to practice coitus interruptus while the Qur'an was being revealed. Ishaq added: Sufyan said: If it had been something forbidden, the Qur'an would have prohibited us from it.
