Should it so happen that we come into contact with one of the Companions of the Messenger of Allah (peace be upon him) we shall ask him about what is talked about taqdir (Divine Decree). Accidentally we came across Abdullah ibn Umar ibn al-Khattab, while he was entering the mosque. My companion and I surrounded him. One of us (stood) on his right and the other stood on his left. I expected that my companion would authorize me to speak. I therefore said: Abu Abdur Rahman! There have appeared some people in our land who recite the Qur'an and pursue knowledge. And then after talking about their affairs, added: They (such people) claim that there is no such thing as Divine Decree and events are not predestined. He (Abdullah ibn Umar) said: When you happen to meet such people tell them that I have nothing to do with them and they have nothing to do with me. And verily they are in no way responsible for my (belief). Abdullah ibn Umar swore by Him (the Lord) (and said): If any one of them (who does not believe in the Divine Decree) had with him gold equal to the bulk of (the mountain) Uhud and spent it (in the way of Allah), Allah would not accept it unless he affirmed his faith in Divine Decree. He further said: My father, Umar ibn al-Khattab, told me: One day we were sitting in the company of Allah's Apostle (peace be upon him) when there appeared before us a man dressed in pure white clothes, his hair extraordinarily black. There were no signs of travel on him. None amongst us recognized him. At last he sat with the Apostle (peace be upon him) He knelt before him placed his palms on his thighs and said: Muhammad, inform me about al-Islam. The Messenger of Allah (peace be upon him) said: Al-Islam implies that you testify that there is no god but Allah and that Muhammad is the messenger of Allah, and you establish prayer, pay Zakat, observe the fast of Ramadan, and perform pilgrimage to the (House) if you are solvent enough (to bear the expense of) the journey. He (the inquirer) said: You have told the truth. He (Umar ibn al-Khattab) said: It amazed us that he would put the question and then he would himself verify the truth. He (the inquirer) said: Inform me about Iman (faith). He (the Holy Prophet) replied: That you affirm your faith in Allah, in His angels, in His Books, in His Apostles, in the Day of Judgment, and you affirm your faith in the Divine Decree about good and evil. He (the inquirer) said: You have told the truth. He (the inquirer) again said: Inform me about al-Ihsan (performance of good deeds). He (the Holy Prophet) said: That you worship Allah as if you are seeing Him, for though you don't see Him, He, verily, sees you. He (the enquirer) again said: Inform me about the hour (of the Doom). He (the Holy Prophet) remarked: One who is asked knows no more than the one who is inquiring (about it). He (the inquirer) said: Tell me some of its indications. He (the Holy Prophet) said: That the slave-girl will give birth to her mistress and master, that you will find barefooted, destitute goat-herds vying with one another in the construction of magnificent buildings. He (the narrator, Umar ibn al-Khattab) said: Then he (the inquirer) went on his way but I stayed with him (the Holy Prophet) for a long while. He then, said to me: Umar, do you know who this inquirer was? I replied: Allah and His Apostle knows best. He (the Holy Prophet) remarked: He was Gabriel (the angel). He came to you in order to instruct you in matters of religion.

This hadith is narrated to us on the authority of Muhammad b. 'Abdullah b. Numair, on the authority of Muhammad b. Bishr, on the authority of Abd Hayyan al-Taymi with the exception that in this narration (instead of the words (Iza Waladat al'amah rabbaha), the words are (Iza Waladat al'amah Ba'laha), i, e, when slave-girl gives birth to her master.

Ask me (about matters pertaining to religion), but they (the Companions of the Holy Prophet) were too much overawed out of profound respect for him to ask him (anything). In the meanwhile a man came there, and sat near his knees and said: Messenger of Allah, what al-lslam is? -to which he (the Holy Prophet) replied: You must not associate anything with Allah, and establish prayer, pay the poor-rate (Zakat) and observe (the fasts) of Ramadan. He said: You (have) told the truth. He (again) said: Messenger of Allah, what al-Iman (the faith) is? He (the Holy Prophet) said: That you affirm your faith in Allah, His angels, His Books, His meeting, His Apostles, and that you believe in Resurrection and that you believe in Qadr (Divine Decree) in all its entirety, He (the inquirer) said: You (have) told the truth. He (again) said: Messenger of Allah, what al-Ihsan is? Upon this he (the Holy Prophet) said: (Al-Ihsan implies) that you fear Allah as if you are seeing Him, and though you see Him not, verily He is seeing you. He (the inquirer) said: You (have) told the truth. He (the inquirer) said: When there would be the hour (of Doom)? (Upon this) he (the HolyProphet said: The one who is being asked about it is no better informed than the inquirer himself. I, however, narrate some of its signs (and these are): when you see a slave (woman) giving birth to her master - that is one of the signs of (Doom) ; when you see barefooted, naked, deaf and dumb (ignorant and foolish persons) as the rulers of the earth - that is one of the signs of the Doom. And when you see the shepherds of black camels exult in buildings - that is one of the signs of Doom. The (Doom) is one of the five things (wrapped) in the unseen. No one knows them except Allah. Then (the Holy Prophet) recited (the folowing verse): Verily Allah! with Him alone is the knowledge of the hour and He it is Who sends down the rain and knows that which is in the wombs and no person knows whatsoever he shall earn on morrow and a person knows not in whatsoever land he shall die. Verily Allah is Knowing, Aware. He (the narrator, Abu Huraira) said: Then the person stood up an (made his way). The Messenger of Allah (ﷺ) said: Bring him back to me. He was searched for, but they (the Companions of the Holy Prophet) could not find him. The Messenger of Allah (ﷺ) thereupon said: He was Gabriel and he wanted to teach you (things pertaining to religion) when you did not ask (them yourselves).
