وَعَنْ سَلَمَةَ بْنِ الْأَكْوَعِ قَالَ: غَزَوْنَا مَعَ أبي بكر زمن النَّبِي صلى الله عَلَيْهِ وَسلم فبيَّتْناهُم نَقْتُلُهُمْ وَكَانَ شِعَارُنَا تِلْكَ اللَّيْلَةَ: أَمِتْ أَمِتْ. رَوَاهُ أَبُو دَاوُد
We went on an expedition with Abu Bakr in the time of the Prophet. We attacked the enemy by night and killed them, and our war-cry that night was “Put to death; put to death.”
