باب الْقَصْدِ وَالْمُدَاوَمَةِ عَلَى الْعَمَلِ
Sahih al-Bukhari 6468

Narrated Anas bin Malik:

Once Allah's Messenger (ﷺ) led us in prayer and then (after finishing it) ascended the pulpit and pointed with his hand towards the Qibla of the mosque and said, "While I was leading you in prayer, both Paradise and Hell were displayed in front of me in the direction of this wall. I had never seen a better thing (than Paradise) and a worse thing (than Hell) as I have seen today, I had never seen a better thing and a worse thing as I have seen today."

حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ، حَدَّثَنَا مُحَمَّدُ بْنُ فُلَيْحٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ هِلاَلِ بْنِ عَلِيٍّ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ سَمِعْتُهُ يَقُولُ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَلَّى لَنَا يَوْمًا الصَّلاَةَ، ثُمَّ رَقِيَ الْمِنْبَرَ فَأَشَارَ بِيَدِهِ قِبَلَ قِبْلَةِ الْمَسْجِدِ، فَقَالَ ‏ "‏ قَدْ أُرِيتُ الآنَ ـ مُنْذُ صَلَّيْتُ لَكُمُ الصَّلاَةَ ـ الْجَنَّةَ وَالنَّارَ مُمَثَّلَتَيْنِ فِي قُبُلِ هَذَا الْجِدَارِ، فَلَمْ أَرَ كَالْيَوْمِ فِي الْخَيْرِ وَالشَّرِّ، فَلَمْ أَرَ كَالْيَوْمِ فِي الْخَيْرِ وَالشَّرِّ ‏"‏‏.‏
