Translation

Ibn 'Awn said: I wrote to Nafi' asking him about the attack on the polytheists without a prior call at the time of fighting. So he wrote back to me stating that this was in the early days of Islam, and that the Prophet of Allah (ﷺ) made a sudden raid upon Banu Al-Mustaliq while they were heedless and their cattle were being watered at the place of water. He fought their combatants, captured their women and children, and on that day he acquired Juwayriyah bint Al-Harith. 'Abdullah narrated this to me, and he was in that army.
