Sunan Ibn Majah, Volume 4, Book 24, Hadith 2840 (DarusSalam) ⓘ

It was narrated from Iyas bin Salamah bin Awka’, that his father said: “We attacked Hawazin, with Abu Bakr, during the time of the Prophet, and we arrived at an oasis belonging to Bani Fazarah during the last part of the night. We attacked at dawn, raiding the people of the oasis, and killed them, nine or seven households.”

حَدَّثَنَا مُحَمَّدُ بْنُ إِسْمَاعِيلَ، أَنْبَأَنَا وَكِيعٌ، عَنْ عِكْرِمَةَ بْنِ عَمَّارٍ، عَنْ إِيَاسِ بْنِ سَلَمَةَ بْنِ الأَكْوَعِ، عَنْ أَبِيهِ، قَالَ غَزَوْنَا مَعَ أَبِي بَكْرٍ هَوَازِنَ عَلَى عَهْدِ النَّبِيِّ صلى الله عليه وسلم فَأَتَيْنَا مَاءً لِبَنِي فَزَارَةَ فَعَرَّسْنَا حَتَّى إِذَا كَانَ عِنْدَ الصُّبْحُ شَنَنَّاهَا عَلَيْهِمْ غَارَةً فَأَتَيْنَا أَهْلَ مَاءٍ فَبَيَّتْنَاهُمْ فَقَتَلْنَاهُمْ تِسْعَةً أَوْ سَبْعَةَ أَبْيَاتٍ ‏.‏
