Hadith 5868

Anas b. Malik told that Abu Bakr as-Siddiq said: I looked at the feet of the polytheists above our heads when we were in the cave and said, "Messenger of God, if one of them were to look at his foot he would see us." He replied, "Abd Bakr, what do you think of two people along with whom God makes a third?" (Bukhari and Muslim.)
