Narrated Al-Mughira bin Shu'ba:
Nobody asked the Prophet as many questions as I asked regarding Ad-Dajjal. The Prophet ﷺ said to me, "What worries you about him?" I said, "Because the people say that he will have a mountain of bread and a river of water with him (i.e. he will have abundance of food and water)" The Prophet ﷺ said, "Nay, he is too mean to be allowed such a thing by Allah"' (but it is only to test mankind whether they believe in Allah or in Ad-Dajjal.)
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا أَيُّوبُ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أُرَاهُ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ
" أَعْوَرُ عَيْنِ الْيُمْنَى، كَأَنَّهَا عِنَبَةٌ طَافِيَةٌ ".
