The Messenger of Allah ﷺ one day led us in the prayer. and when he completed the Prayer he turned his face towards us and said: 0 People, I am your Imam, so do not precede me in bowing and prostration and in standing and turning (faces, i. e. In pronouncing salutation), for I see you in front of me and behind me, and then said: By Him in Whose hand Is the life of Muhammad, if you could see what I see, you would have laughed little and wept much more. They said: What did you see, Messenger of Allah? He replied: (I saw) Paradise and Hell.  

صَلَّى بِنَا رَسُولُ اللَّهِ ﷺ ذَاتَ يَوْمٍ فَلَمَّا قَضَى الصَّلاَةَ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ أَيُّهَا النَّاسُ إِنِّي إِمَامُكُمْ فَلاَ تَسْبِقُونِي بِالرُّكُوعِ وَلاَ بِالسُّجُودِ وَلاَ بِالْقِيَامِ وَلاَ بِالاِنْصِرَافِ فَإِنِّي أَرَاكُمْ أَمَامِي وَمِنْ خَلْفِي ثُمَّ قَالَ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَوْ رَأَيْتُمْ مَا رَأَيْتُ لَضَحِكْتُمْ قَلِيلاً وَلَبَكَيْتُمْ كَثِيرًا قَالُوا وَمَا رَأَيْتَ يَا رَسُولَ اللَّهِ قَالَ رَأَيْتُ الْجَنَّةَ وَالنَّارَ  

This hadith is narrated by Anas with another chain of transmitters, and in the hadith transmitted by Jarir there is no mention of" turning (faces)".  

عَنِ النَّبِيِّ ﷺ بِهَذَا الْحَدِيثِ وَلَيْسَ فِي حَدِيثِ جَرِيرٍ وَلاَ بِالاِنْصِرَافِ  

The Messenger of Allah ﷺ said: Does the man who lifts his head ahead of the Imam (from prostration) not fear that Allah may change his head into the head of an ass?  

مُحَمَّدٌ ﷺ أَمَا يَخْشَى الَّذِي يَرْفَعُ رَأْسَهُ قَبْلَ الإِمَامِ أَنْ يُحَوِّلَ اللَّهُ رَأْسَهُ رَأْسَ حِمَارٍ  

The Messenger of Allah ﷺ said: Does the man who lifts his head before the Imam not fear that Allah may change his face into that of an ass?  

قَالَ رَسُولُ اللَّهِ ﷺ مَا يَأْمَنُ الَّذِي يَرْفَعُ رَأْسَهُ فِي صَلاَتِهِ قَبْلَ الإِمَامِ أَنْ يُحَوِّلَ اللَّهُ صُورَتَهُ فِي صُورَةِ حِمَارٍ  

" Allah may make his face like the face of an ass."  

عَنِ النَّبِيِّ ﷺ بِهَذَا غَيْرَ أَنَّ فِي حَدِيثِ الرَّبِيعِ بْنِ مُسْلِمٍ أَنْ يَجْعَلَ اللَّهُ وَجْهَهُ وَجْهَ حِمَارٍ
