It was narrated that Anas bin Malik said:
"The Messenger of Allah ﷺ led us in prayer one day, then he turned to face us and said: 'I am now your imam, so do not hasten to bow or prostrate or stand or leave before I do. I can see you in front of me and behind me.' Then he said: 'By the One in Whose Hand is my soul, if you had seen what I have seen, you would laugh little and weep much.' We said: 'What have you seen, O Messenger of Allah ﷺ?' He said: 'Paradise and Hell.'"
أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنِ الْمُخْتَارِ بْنِ فُلْفُلٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ صَلَّى بِنَا رَسُولُ اللَّهِ ﷺ ذَاتَ يَوْمٍ ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ " إِنِّي إِمَامُكُمْ فَلاَ تُبَادِرُونِي بِالرُّكُوعِ وَلاَ بِالسُّجُودِ وَلاَ بِالْقِيَامِ وَلاَ بِالاِنْصِرَافِ فَإِنِّي أَرَاكُمْ مِنْ أَمَامِي وَمِنْ خَلْفِي " . ثُمَّ قَالَ " وَالَّذِي نَفْسِي بِيَدِهِ لَوْ رَأَيْتُمْ مَا رَأَيْتُ لَضَحِكْتُمْ قَلِيلاً وَلَبَكَيْتُمْ كَثِيرًا " . قُلْنَا مَا رَأَيْتَ يَا رَسُولَ اللَّهِ قَالَ " رَأَيْتُ الْجَنَّةَ وَالنَّارَ " .
