Sahih al-Bukhari, 2541

Narrated Ibn `Aun:I wrote a letter to Nafi` and Nafi` wrote in reply to my letter that the Prophet (ﷺ) had suddenly attacked Bani Mustaliq without warning while they were heedless and their cattle were being watered at the places 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 and that Ibn `Umar was in that army

Rapporté par Ibn `Aun : J’ai écrit une lettre à Nafi`, et Nafi` m’a répondu que le Prophète (ﷺ) avait attaqué soudainement Bani Mustaliq sans prévenir, alors qu’ils étaient inattentifs et que leurs troupeaux étaient en train d’être abreuvés. Les hommes combattants ont été tués et les femmes et enfants ont été faits prisonniers ; le Prophète (ﷺ) a obtenu Juwairiya ce jour-là. Nafi` a dit qu’Ibn `Umar lui avait raconté ce récit et qu’Ibn `Umar faisait partie de cette armée
