Chapter: Permissibility of raiding the Kuffar, who have been reached with the call of Islam, without giving prior warning

Ibn 'Aun reported: I wrote to Nafi' inquiring from him whether it was necessary to extend (to the disbelievers) an invitation to accept (Islam) before meeting them in fight. He wrote (in reply) to me that it was necessary in the early days of Islam. The Messenger of Allah (ﷺ) made a raid upon Banu Mustaliq while they were unaware and their cattle were having a drink at the water. He killed those who fought and imprisoned others. On that very day, he captured Juwairiya bint al-Harith. Nafi' said that this tradition was related to him by'Abdullah bin 'Umar (RA) who (himself) was among the raiding troops.

This hadith has been narrated on the authority of Ibn 'Aun and the name of Juwairiya bint al-Harith was mentioned beyond any doubt.
