[Machine] The Messenger of Allah ﷺ said, "Indeed, I have already begun, so do not precede me in the bowing or in the prostration. For indeed, no matter how much I precede you in the bowing, you will catch up with me when I rise, and no matter how much I precede you in the prostration, you will catch up with me when I rise."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «إِنِّي قَدْ بَدَّنْتُ فَلَا تَسْبِقُونِي بِالرُّكُوعِ وَلَا بِالسُّجُودِ فَإِنِّي مَهْمَا أَسْبِقُكُمْ حِينَ أَرْكَعُ تُدْرِكُونِي حِينَ أَرْفَعُ وَمَهْمَا أَسْبِقُكُمْ حِينَ أَسْجُدُ تُدْرِكُونِي حِينَ أَرْفَعُ»  

The Prophet ﷺ said, "Isn't he who raises his head before the Imam afraid that Allah may transform his head into that of a donkey or his figure (face) into that of a donkey?" (Using translation from Bukhārī 691)  

قَالَ رَسُولُ اللَّهِ ﷺ «أَمَا يَخْشَى أَحَدُكُمْ أَوْ أَلَا يَخْشَى أَحَدُكُمْ إِذَا رَفَعَ رَأْسَهُ قَبْلَ الْإِمَامِ أَنْ يَجْعَلَ اللَّهُ رَأْسَهُ رَأْسَ حِمَارٍ أَوْ صُورَتَهُ صُورَةَ حِمَارٍ؟ »  

[Machine] Indeed, the Prophet ﷺ encouraged them to pray and forbade them from preceding him in the bowing and prostration when he was leading them in prayer. He also instructed them to not leave before he finishes his prayer and he said, "I see you from behind me and in front of me."  

أَنَّ النَّبِيَّ ﷺ حَثَّهُمْ عَلَى الصَّلَاةِ وَنَهَاهُمْ أَنْ يَسْبِقُوهُ إِذَا كَانَ يَؤُمُّهُمْ بِالرُّكُوعِ وَالسُّجُودِ وَأَنْ يَنْصَرِفُوا قَبْلَ انْصِرَافِهِ مِنَ الصَّلَاةِ وَقَالَ «إِنِّي أَرَاكُمْ مِنْ خَلْفِي وَأَمَامِي»
