Hadith on Fitnah: Killing, upheaval, sin before the Hour

Abu Huraira reported: The Prophet, peace and blessings be upon him, said, “Time will pass rapidly, knowledge will be withdrawn, tribulations will prevail, greed will be cast into hearts, and there will be many upheavals.” They said, “What is upheaval?” The Prophet said, “It is killing.”
