Narrated Anas bin Malik:

The Prophet led us in prayer and then went up to the pulpit and beckoned with both hands towards the Qibla of the mosque and then said, "When I started leading you in prayer, I saw the display of Paradise and Hell on the wall of the mosque (facing the Qibla). I never saw good and bad as I have seen today." He repeated the last statement thrice.

حَدَّثَنَا مُحَمَّدُ بْنُ سِنَانٍ، قَالَ حَدَّثَنَا فُلَيْحٌ، قَالَ حَدَّثَنَا هِلاَلُ بْنُ عَلِيٍّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ صَلَّى لَنَا النَّبِيُّ ﷺ ثُمَّ رَقَا الْمِنْبَرَ، فَأَشَارَ بِيَدَيْهِ قِبَلَ قِبْلَةِ الْمَسْجِدِ ثُمَّ قَالَ " لَقَدْ رَأَيْتُ الآنَ مُنْذُ صَلَّيْتُ لَكُمُ الصَّلاَةَ الْجَنَّةَ وَالنَّارَ مُمَثَّلَتَيْنِ فِي قِبْلَةِ هَذَا الْجِدَارِ، فَلَمْ أَرَ كَالْيَوْمِ فِي الْخَيْرِ وَالشَّرِّ " ثَلاَثًا.
