Chapter: Ad-Dajjal Is Very Insignificant Before Allah
(22)
باب فِي الدَّجَّالِ وَهُوَ أَهْوَنُ عَلَى اللَّهِ عَزَّ وَجَلَّ
Sahih Muslim 2939 a

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.
حَدَّثَنَا شِهَابُ بْنُ عَبَّادٍ الْعَبْدِيُّ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ حُمَيْدٍ الرُّؤَاسِيُّ، عَنْ إِسْمَاعِيلَ، بْنِ أَبِي خَالِدٍ عَنْ قَيْسِ بْنِ أَبِي حَازِمٍ، عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ، قَالَ مَا سَأَلَ أَحَدٌ النَّبِيَّ صلى الله عليه وسلم عَنِ الدَّجَّالِ أَكْثَرَ مِمَّا سَأَلْتُ قَالَ ‏"‏ وَمَا يُنْصِبُكَ مِنْهُ إِنَّهُ لاَ يَضُرُّكَ ‏"‏ ‏.‏ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّهُمْ يَقُولُونَ إِنَّ مَعَهُ الطَّعَامَ وَالأَنْهَارَ قَالَ ‏"‏ هُوَ أَهْوَنُ عَلَى اللَّهِ مِنْ ذَلِكَ ‏"‏ ‏.‏
