Sahih Al-Bukhari HadithHadith 5.358Narrated byJubair bin Mutim
I heard the Prophet reciting Surat-at-Tur in Maghrib prayer, and that was at a time when belief was first planted in my heart. The Prophet while speaking about the war prisoners of Badr, said, "Were Al-Mutim bin Adi alive and interceded with me for these filthy people, I would definitely forgive them for his sake."
Narrated Said bin Al-Musaiyab:
When the first civil strife (in Islam) took place because of the murder of 'Uthman, it left none of the Badr warriors alive.
When the second civil strife, that is the battle of Al-Harra, took place, it left none of the Hudaibiya treaty companions alive.
Then the third civil strife took place and it did not subside till it had exhausted all the strength of the people.
*** The murderers of Jews, Christians and Unbelievers, who were ALLArabs, were themselves subsequently exterminated by the sword ***
