Abu Huraira reported Allah's Messenger (may peace be upon him) as saying: (When) the time would draw close to the Last Hour, knowledge would be snatched away, turmoil would be rampant, miserliness would be put (in the hearts of the people) and therewould be much bloodshed. They said: What is al-harj? Thereupon he said: It is bloodshed.
