I wrote a letter to Nafi` and Nafi` wrote in reply to my letter that the Prophet (ﷺ) had suddenly attackedBani Mustaliq without warning while they were heedless and their cattle were being watered at theplaces of water. Their fighting men were killed and their women and children were taken as captives;the Prophet (ﷺ) got Juwairiya on that day. Nafi` said that Ibn `Umar had told him the above narration andthat Ibn `Umar was in that army.
