Abu Umamah bin Sahl bin Hunaif narrated from some of the companions of the Prophet ﷺ that the Prophet ﷺ said:

"While I was sleeping I saw people presented before me, and that they were wearing shirts. Some of them (the shirts) reaching their breasts, and some of them reaching below that." He said: "Then 'Umar was presented before me and he was wearing a shirt that was dragging." They said: "How did you interpret that O Messenger of Allah?" He said: "The religion."

حَدَّثَنَا الْحُسَيْنُ بْنُ مُحَمَّدٍ الْجُرَيْرِيُّ الْبَلْخِيُّ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي أُمَامَةَ بْنِ سَهْلِ بْنِ حُنَيْفٍ، عَنْ بَعْضِ، أَصْحَابِ النَّبِيِّ ﷺ أَنَّ النَّبِيَّ ﷺ قَالَ " بَيْنَمَا أَنَا نَائِمٌ رَأَيْتُ النَّاسَ يُعْرَضُونَ عَلَىَّ وَعَلَيْهِمْ قُمُصٌ مِنْهَا مَا يَبْلُغُ الثُّدِيَّ وَمِنْهَا مَا يَبْلُغُ أَسْفَلَ مِنْ ذَلِكَ فَعُرِضَ عَلَىَّ عُمَرُ وَعَلَيْهِ قَمِيصٌ يَجُرُّهُ " . قَالُوا فَمَا أَوَّلْتَهُ يَا رَسُولَ اللَّهِ قَالَ " الدِّينَ " .
