Abu Sa`id Khudri reported:
One who is better than I informed me, that Allah's Messenger ( صلی اللہ علیہ وسلم ) said to `Ammar as he was digging the ditch (on the ocassion of the Battle of the Ditch) wiping over his head: O son of Summayya, you will be involved in trouble and a group of the rebels would kill you.
