Arabic hadith text
وَعَنْ أَنَسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى الله عَلَيْهِ وَسلم: يَوْمئِذٍ يَوْمَ حُنَيْنٍ: «مَنْ قَتَلَ كَافِرًا فَلَهُ سَلَبُهُ» فَقَتَلَ أَبُو طَلْحَةَ يَوْمَئِذٍ عِشْرِينَ رَجُلًا وَأَخَذَ أسلابهم. رَوَاهُ الدَّارمِيّ
Translation
Anas reported God’s Messenger as saying on that day, meaning the day of Hunain, “He who kills an infidel gets what he takes from him.” Abu Talha killed twenty men that day and got what was taken from them. Darimi transmitted it.
