Al-Mughirah bin Shu'bah (May Allah be pleased with him) said:
No one asked the Messenger of Allah (ﷺ) more about Dajjal than I asked him. He said to me, "He will not harm you." I said: "O Messenger of Allah, it is reported that he will have with him a mountain of bread and a river full of water." Thereupon he said, "He (Dajjal) is far too worthless and insignificant near Allah (to let him deceive the believers)."[Al-Bukhari and Muslim].
