Anas told that God's messenger led them in prayer one day, then mounted the pulpit and, pointing to the qibla in the mosque, said, "I have just now been shown, since I led you in prayer, paradise and hell pictured in front of this wall, and I have never seen such good and evil as I have seen to-day." Bukhari transmitted it.

عَنْ أَنَسٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صلى بِنَا يَوْمًا الصَّلَاةَ ثُمَّ رَقِيَ الْمِنْبَرَ فَأَشَارَ بِيَدِهِ قِبَلَ قِبْلَةِ الْمَسْجِدِ فَقَالَ: «قَدْ أُرِيتُ الْآنَ مُذْ صَلَّيْتُ لَكُمُ الصَّلَاةَ الْجَنَّةَ وَالنَّارَ مُمَثَّلَتَيْنِ فِي قِبَلِ هَذَا الْجِدَارِ فَلَمْ أَرَ كَالْيَوْمِ فِي الْخَيْر وَالشَّر» . رَوَاهُ البُخَارِيّ
