Ibn ‘Awn said “I wrote to Nafi’ asking him about summoning the polytheists (to Islam) at the time of fighting. So, he wrote to me “This was in the early days of Islam. The Prophet of Allaah(ﷺ) attacked Banu Al Mustaliq while they were inattentive and their cattle were drinking water. So their fighters were killed and the survivors (i.e., women and children) were taken prisoners. On that day Juwairiyyah daughter of Al Harith was obtained. ‘Abd Allaah narrated this to me, he was in that army.”
Abu Dawud said “This is a good tradition narrtted by Ibn ‘Awn from Nafi’ and no one shared him in narrating it.”
