Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Jews came to the Noble Prophet (peace and blessings be upon him) and said: O Abul Qasim! We will ask you about five things; if you answer them, we will recognize that you are a true Prophet and we will follow you. You took a covenant from them in the same way that Yaqub (peace be upon him) took a covenant from his sons, when they said that Allah is a witness over what we are saying. The Prophet (peace and blessings be upon him) said: Present your questions.

(1) They said: Tell us the sign of a Prophet. The Prophet (peace and blessings be upon him) said: The eyes of a Prophet sleep, but his heart does not sleep.

(2) They said: Tell us how male and female are created? The Prophet (peace and blessings be upon him) said: The essence of water from man and woman mixes; when the man’s water prevails over the woman’s water, a male is born, and when the woman’s essence of water prevails, a female is born.

(3) They said: Tell us what Yaqub (peace be upon him) made unlawful for himself? The Prophet (peace and blessings be upon him) said: He had the disease of sciatica; only the milk of she-camels suited him, so when he recovered, he made the meat of camels unlawful for himself. They said: You have spoken the truth.

(4) They said: Tell us, what is thunder? The Prophet (peace and blessings be upon him) said: It is an angel among the angels of Allah, who is in charge of the clouds. In the hand of this angel is a whip of fire, with which he drives the clouds to the place where Allah has commanded. They said: What is the sound that is heard? The Prophet (peace and blessings be upon him) said: It is the sound of that whip. They said: You have spoken the truth.

(5) They said: One thing remains; if you answer it, we will pledge allegiance to you. It is that every Prophet has an angel appointed to him who brings him goodness, that is, revelation. Tell us, who is your angel companion? The Prophet (peace and blessings be upon him) said: Jibreel (peace be upon him). This time they said: Jibreel, he brings war, fighting, and punishment; he is our enemy. If you had said Mika’il, who descends with mercy, vegetation, and rain, then it would have been acceptable. At that time, Allah revealed this verse: {قُلْ مَنْ کَانَ عَدُوًّا لِّجِبْرِیْلَ فَاِنَّہ نَزَّلَہ عَلٰی قَلْبِکَ بِاِذْنِ اللّٰہِ مُصَدِّقًا لِّمَا بَیْنَیَدَیْہِ وَھُدًی وَّبُشْرٰی لِلْمُؤْمِنِیْنَ۔} … Say: Whoever is an enemy to Jibreel, for indeed he has brought it (the Qur’an) down upon your heart by Allah’s permission, confirming what was before it and as guidance and glad tidings for the believers. (Surah Al-Baqarah: 97)
