The proof from the Sunnah is the famous hadeeth of Jibreel narrated by 'Umar as he said: “One day while we were sitting with the Messenger of Allah, there appeared before us a man with extremely white clothes and extremely black hair. There were no signs of travel on him and none of us knew him. He sat in front of the Prophet and put his hands on his own thighs. He said: “O Muhammad, tell me about Islam”. The Messenger of Allah said: “Islam is to testify that there is none worthy of worship except Allah and that Muhammad is the Messenger of Allah, to establish the prayers, to pay the zakat (charity), to fast (the month of) Ramadhaan, and to do the pilgrimage at the House if you have the means to do so.” He said: “You are correct”. We were amazed that he asks the question and then he corrects it. He said: “Tell me about Imaan”. He responded, “It is to believe in Allah, His angels, His books, His messengers, the Last Day, and to believe in the divine decree, (both) the good and the evil”. He said: “You are correct”. He said: “Tell me about Ihsaan”. He answered: “It is that you worship Allah as if you see Him. And even though you do not see Him, you know He certainly sees you”. He said: “Tell me about (the time of) the Hour”. He answered, “The one being asked does not know more than the one asking”. He said: “Tell me about its signs”. He answered: “The slave-girl will give birth to her master; and you will see the barefooted, scantily clothed, destitute shepherds competing in constructing high buildings”. Then, he went away. I stayed for a long time. Then, he said: “O 'Umar, do you know who the questioner was?” I said: “Allah and His Messenger know best”. He said: “It was (the Angel) Jibreel who came to teach you your religion” (Muslim).
This Hadeeth is a proof for the pillars of Islaam, Imaan, and Ihsaan. His statement “The one being asked does not know more than the one asking” is a proof that no one knows when the Day of Judgement will be except Allah.
His saying “the Slave girl will give birth to his master” has been interpreted as:
- Disobedience to parents increases
- Slavery increases
- Changing of roles (in the society)
- A king has relations with his female slave and she gives birth to his son. Once the king dies, his son becomes the king. Thus, he becomes his mother's master
