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].
وعن المغيرة بن شعبة رضي الله عنه قال: ما سأل أحد رسول الله صلى الله عليه وسلم عن الدجال أكثر مما سألته؛ وإنه قال لي: "مايضرك؟ "قلت: إنهم يقولون: إن معه جبل خبز ونهر ماء! قال: "هو أهون على الله من ذلك" ((متفق عليه)).
