From Sahih Muslim (Hadith 7379):
Mughira b. Shu'ba reported that none asked Allah's Apostle (ﷺ) about Dajjal more than I asked him. I (one of the narrators other than Mughira b. Shu'ba) said:What did you ask? Mughira replied: I said that the people alleged that he would have a mountain load of bread and mutton and rivers of water. Thereupon he said: He would be more insignificant in the eye of Allah compared with all this
