What was the result when the Prophet Muhammad (saw) invoked evil upon Suraqa bin Ju'shum?
 Narrated Al-Bara:                     The Prophet came from Mecca with Abu Bakr. Abu Bakr said "We passed by a shepherd and at that time Allah's Apostle was thirsty. I milked a little milk in a bowl and Allah's Apostle drank till I was pleased. Suraqa bin Ju'shum came to us riding a horse (chasing us). The Prophet invoked evil upon him, whereupon Suraqa requested him not to invoke evil upon him, in which case he would go back. The Prophet agreed.
