Nafi told that two men came to Ibn `Umar during the civil war. of Ibn az-Zubair and said, "The people have done what you see, and you are `Umar's son and the companion of God's messenger, so what prevents you from going forth [1] ?" He replied, "What prevents me is the fact that God has made it unlawful for me to shed my brother Muslim's blood." They asked if God most high had not said, "And fight with them till there is no dissension [2] ," to which Ibn `Umar replied, "We have fought till there was no dissension and the religion was God's, but you want to fight so that there may be dissension and the religion may pertain to someone other than God." i.e., in revolt. Quran; 2:193, 8:39 Bukhari transmitted it.
