O Abul-Qasim, we are going to ask you about five things; if you tell us what we know about them, then you are indeed a Prophet (ﷺ) and we will follow you. He took a promise from them as Isra'eel took a promise from his sons when they said: "Allah is the Witness to what we have said” (Yoosuf 12:66). He said: "Let's hear it." They said: Tell us about the sign of a Prophet. He said: “His eyes sleep but his heart does not sleep.” They said: Tell us how can a woman give birth to a female or a male? He said: “The two waters meet and if the man's water prevails over the woman's, she will give birth to a male, but if the woman's water prevails, she will give birth to a female." They said: Tell us what Isra'eel forbade to himself. He said: “He suffered from sciatica and could not find anything to help him except the milk of such and such" - my father said: meaning camel's milk so he forbade (camel meat) to himself." They said: You are right. They said: Tell us about thunder. He said: “One of the angels of Allah, may He be glorified and exalted, is in charge of the clouds. In his hand is a whip of fire with which he collects the clouds and drives them wherever Allah commands.” They said: What is this sound that we hear? He said: “His voice.” They said: You are right; there is only one question left, and it is the one that will decide whether we swear allegiance to you. There is no Prophet but he has an angel who brings news to him; tell us who your angel is. He said: "Jibreel (عليه السلام).” They said: Jibreel! He is the one who brings down war, fighting and punishment; he is our enemy. If you had said Mika'eel, who brings down mercy, plants and rain, it would have been fine. Then Allah, may He be glorified and exalted, revealed the words: “Whoever is an enemy to Jibreel (Gabriel) (let him die in his fury), for indeed he has brought it (this Qur'an) down to your heart by Allah's Permission, confirming what came before it [i.e., the Tawrat (Torah) and the Injeel (Gospel) and guidance and glad tidings for the believers” (al-Baqarah 2:97).
