سنن النسائي

It was narrated that Abu Dharr said; "The truthful one whom people believe told me: 'The people will be gathered in three groups: A group who will be riding, well fed and well clothed; a group whom the angels will drag on their faces and whom the fire will drive; and a group who will be walking with difficulty. Allah will send a disease to kill all the riding beasts and none will remain, until a man would give a garden for a she-camel but he will not be able to have it.
