He reported God's messenger as saying, "By Him in whose hand my soul is, the world will not pass away till a day comes to mankind when the killer will not know why he killed, or the one who is killed why he was killed." He was asked how that could be and replied, "There will be turmoil, and the killer and the one who is killed will go to hell." Muslim transmitted it.
Reported by Muslim (No. 2908b). Cited in Mishkat al-Masabih (No. 5390).
Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: ''By Him in Whose hand is my soul, a time would come upon the people when the killer would not know why he killed and the victim would not know why he was killed.''
