They thus lived in peace for sometime but ulterior motives stretching back to pre-Islamic period ignited by unabated fire of revenge triggered fresh hostilities. Banu Bakr, without caring a bit for the provisions of the treaty, attacked Banu Khuza'a in a place called Al-Wateer in Sha‘ban, 8 A.H. Quraish helped Banu Bakr with men and arms taking advantage of the dark night. Pressed by their enemies, the tribesmen of Khuza‘ah sought the Holy Sanctuary, but here too, their lives were not spared, and, contrary to all accepted traditions, Nawfal, the chief of Banu Bakr, chasing them in the sanctified area — where no blood should be shed — massacred his adversaries.
