It is narrated from Zayd bin Aslam (may Allah have mercy on him) concerning the saying of Allah Almighty: "Have you not seen those who left their homes in their thousands, fearing death" up to: "And Allah is All-Knowing of the wrongdoers" [Surah al-Baqarah: 243 - 246] , that he said: "Allah Almighty revealed to their prophet that among the children of so-and-so there is a man through whom Allah Almighty will have Jalut killed, and his sign is that you will place this horn on his head and water will gush forth from it. So he (the prophet) came to that man and said: Allah Almighty has revealed to me that among your children there is a man through whom Allah Almighty will have Jalut killed. He said: Yes, O Prophet of Allah! Then he presented before him twelve men like pillars (strong and tall), among whom was one man more handsome than all of them. So the prophet began to bring them before the horn, but he saw no sign. At this the prophet said: Do you have any children besides these? The man said: Yes, O Prophet of Allah! I have a son of short stature; I felt ashamed to show him to people, so I have sent him among the goats (to graze them). The prophet asked: Where is he? He said: He is in such and such a valley. So the prophet went out to him (and when he saw him) said: Indeed this is the one. Then he placed the horn on his head and it gushed forth (with water)."
