Anas reported: One day the Messenger of Allah, peace be upon him, led us in prayer. He turned his face to us and said, “O people, I am your leader so do not go ahead of me in bowing, prostration, standing and turning, for I see you in front of me and behind me.” Then he said, “By him in Whose Hand is the soul of Muhammad, if you could see what I see then you would have laughed little and wept more.” They said, “O Messenger of Allah, what do you see?” He said, “Paradise and Hellfire.”
[Sahih Muslim, Book 4, Number 857]
عَنْ أَنَسٍ قَالَ صَلَّى بِنَا رَسُولُ اللَّهِ صَلَّى
اللَّهُ عَلَيْهِ وَسَلَّمَ ذَاتَ يَوْمٍ فَلَمَّا قَضَى الصَّلَاةَ
أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ أَيُّهَا النَّاسُ إِنِّي
إِمَامُكُمْ فَلَا تَسْبِقُونِي بِالرُّكُوعِ وَلَا بِالسُّجُودِ وَلَا
بِالْقِيَامِ وَلَا بِالِانْصِرَافِ فَإِنِّي أَرَاكُمْ أَمَامِي وَمِنْ
خَلْفِي ثُمَّ قَالَ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَوْ رَأَيْتُمْ مَا رَأَيْتُ لَضَحِكْتُمْ قَلِيلًا وَلَبَكَيْتُمْ كَثِيرًا قَالُوا وَمَا رَأَيْتَ يَا رَسُولَ اللَّهِ قَالَ رَأَيْتُ الْجَنَّةَ وَالنَّارَ
صحيح مسلم كتاب الصلاة باب تحريم سبق الإمام بركوع أو سجود ونحوهما
