Sunan Ibn Majah, Volume 4, Book 24, Hadith 2829 (DarusSalam) ⓘ
It was narrated that Lahi’ah bin ‘Uqbah said: “I heard Abul-Ward, the Companion of the Messenger of Allah, say: ‘Beware of the troop which, when it meets (the enemy) it flees, and when it takes spoils of war, it steals from it.’”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ، عَنِ ابْنِ لَهِيعَةَ، أَخْبَرَنِي يَزِيدُ بْنُ أَبِي حَبِيبٍ، عَنْ لَهِيعَةَ بْنِ عُقْبَةَ، قَالَ سَمِعْتُ أَبَا الْوَرْدِ، صَاحِبَ النَّبِيِّ صلى الله عليه وسلم يَقُولُ إِيَّاكُمْ وَالسَّرِيَّةَ الَّتِي إِنْ لَقِيَتْ فَرَّتْ وَإِنْ غَنِمَتْ غَلَّتْ .
