What did the Prophet Muhammad (peace be upon him) say when Abu Bakr expressed his fear of the pagans discovering them in the cave?
 Narrated Abu Bakr:                     I was in the company of the Prophet in the cave, and on seeing the traces of the pagans, I said, "O Allah's Apostle If one of them (pagans) should lift up his foot, he will see us." He said, "What do you think of two, the third of whom is Allah?"
