Narrated Abu Huraira:
The Prophet said, "Time will pass rapidly, good deeds will decrease, miserliness will be thrown (in the hearts of the people) afflictions will appear and there will be much 'Al-Harj." They said, "O Allah's Apostle! What is "Al-Harj?" He said, "Killing! Killing!" (See Hadith No. 63, Vol. 8)
