Musnad Ahmad Hadith 19636

Usayd says that once we were returning from Isfahan with Abu Musa (may Allah be pleased with him). We were traveling at a fast pace when "Aqilah" arrived. Abu Musa (may Allah be pleased with him) said, "Is there any young man who can help the young woman dismount from her mount?" I said, "Why not?" So I brought her mount near a tree and helped her dismount, then came and sat with the people. He said, "Shall I not narrate to you a hadith that the Noble Prophet (ﷺ) used to narrate to us?" We said, "Why not? May Allah's mercy descend upon you." He said, "The Noble Prophet (ﷺ) used to tell us that before the Hour, 'Harj' will occur." The people asked, "What is meant by 'Harj'?" The Noble Prophet (ﷺ) said, "Killing." The people asked, "Even more than the number we kill? We used to kill more than seventy thousand people every year!" The Noble Prophet (ﷺ) said, "It does not mean killing the polytheists, rather it means killing one another, to the extent that a man will kill his neighbor, his uncle, his brother, and his cousin." The people asked, "Will our intellects be with us at that time?" The Noble Prophet (ﷺ) said, "The intellects of the people of that time will be taken away, and foolish people will remain who will think they are upon a religion, but they will not be upon any religion." Abu Musa (may Allah be pleased with him) says, "By the One in Whose hand is my soul, if that time comes, I will not find any way out for myself or for you except that we leave it as we entered it, and do not become involved in anyone's killing or wealth."
