Ibn 'Awn said: I wrote to Nafi' asking him about calling to Islam before combat, so he wrote to me that this was at the beginning of Islam. The Prophet of Allah (PBUH) raided Banu Al-Mustaliq while they were unaware and their livestock were drinking water at the watering place, so he killed their fighters and took their women and children right hand possessions, and on that day he captured Juweiriyah, the daughter of Al-Harith [later to be he Prophet's wife]. Nafi' said: 'Abdullah told me about that, and he was in that army.
