Chapter : The Last Hour would not come until a person would pass by a grave and wish that he should have been the occupant of that grave because of this calamity.
Abu Huraira reported Allah’s Messenger (may peace be upon him) as saying: You shall fight in the hours to come against a nation wearing shoes made of hair and faces like hammered shields, with red complexion and small eyes.
