Narrated Abu Sa`id Al-Khudri: I heard Allah's Messenger (ﷺ) saying, "While I was sleeping, I saw (in a dream) the people being displayed before me, wearing shirts, some of which (were so short that it) reached as far as their breasts and some reached below that. Then `Umar bin Al-Khattab was shown to me and he was wearing a shirt which he was dragging (behind him)." They asked. What have you interpreted (about the dream)? O Allah's Messenger (ﷺ)?" He said, "The religion."

حَدَّثَنَا سَعِيدُ بْنُ عُفَيْرٍ، حَدَّثَنِي اللَّيْثُ، حَدَّثَنِي عُقَيْلٌ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي أَبُو أُمَامَةَ بْنُ سَهْلٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ـ رضى الله عنه ـ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏"‏ بَيْنَا أَنَا نَائِمٌ رَأَيْتُ النَّاسَ عُرِضُوا عَلَىَّ، وَعَلَيْهِمْ قُمُصٌ، فَمِنْهَا مَا يَبْلُغُ الثَّدْىَ، وَمِنْهَا مَا يَبْلُغُ دُونَ ذَلِكَ، وَعُرِضَ عَلَىَّ عُمَرُ بْنُ الْخَطَّابِ وَعَلَيْهِ قَمِيصٌ يَجْتَرُّهُ ‏"‏‏.‏ قَالُوا فَمَا أَوَّلْتَهُ يَا رَسُولَ اللَّهِ قَالَ ‏"‏ الدِّينَ ‏"‏‏.‏
