The Book Pertaining to the Oath, for Establishing the Responsibility of Murders, Fighting, Requital and Blood-Wit (Kitab Al-Kitab Al-Qasama wa'l-Muharaba wa'l-Qisas wa'l-Diyat)
Muslim :: Book 16 : Hadith 4133
Abu Qilaba reported: I was sitting behind 'Umar b. 'Abd al-'Aziz and he said to the people: What do you say about al-Qasama? Thereupon 'Anbasa said: Anas b Malik narrated to us such and such (hadith pertaining to al-Qasama). I said: This is what Anas had narrated to me: People came to Allah's Apostle (may peace be upon him), and the rest of the hadith is the same. When I (Abu Qilaba) finished (the narration of this hadith), 'Anbasa said: Hallowed be Allah. I said: Do you blame me (for telling a lie)? He ('Anbasa) said: No. This is how Anas b Malik narrated to us. O people of Syria, you would not be deprived of good, so long as such (a person) or one like him lives amongst you.
