Mughira b. Shu'ba reported: No one asked Allah's Messenger (ﷺ) more about Dajjil than I asked him. He said: He should not be a source of worry to you for he would not be able to do any harm to you. I said: Allah's Messenger, it is alleged that he would have along with him (abundance of) food and water. Thereupon he said: He would be very insignificant in the eye of Allah (even) with all this.
