“The Prophet ﷺ used to teach us not to bow or prostrate before the Imam; when he says the Takbir then say the Takbir, and when he prostrates, you should prostrate.”  

كَانَ النَّبِيُّ ﷺ يُعَلِّمُنَا أَنْ لاَ نُبَادِرَ الإِمَامَ بِالرُّكُوعِ وَالسُّجُودِ وَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا سَجَدَ فَاسْجُدُوا  

“The Messenger of Allah ﷺ said: ‘Does not the one who raises his head before the Imam fear that Allah may turn his head into the head of a donkey?’”  

رَسُولُ اللَّهِ ﷺ أَلاَ يَخْشَى الَّذِي يَرْفَعُ رَأْسَهُ قَبْلَ الإِمَامِ أَنْ يُحَوِّلَ اللَّهُ رَأْسَهُ رَأْسَ حِمَارٍ؟  

“The Messenger of Allah ﷺ said: ‘I have gained weight, so when I bow, then bow, and when I stand up, then stand up, and when I prostrate, then prostrate. I should never find anyone preceding me in bowing or prostration.’”  

رَسُولُ اللَّهِ ﷺ إِنِّي قَدْ بَدَّنْتُ فَإِذَا رَكَعْتُ فَارْكَعُوا وَإِذَا رَفَعْتُ فَارْفَعُوا وَإِذَا سَجَدْتُ فَاسْجُدُوا وَلاَ أُلْفِيَنَّ رَجُلاً يَسْبِقُنِي إِلَى الرُّكُوعِ وَلاَ إِلَى السُّجُودِ  

“The Messenger of Allah ﷺ said: ‘Do not bow or prostrate before me. No matter how far ahead of you I bow, you will catch up with me when I stand up, and no matter how far ahead of you I prostrate, you will catch up with me when I raise my head. I have become bulky.’”  

رَسُولُ اللَّهِ ﷺ لاَ تُبَادِرُونِي بِالرُّكُوعِ وَلاَ بِالسُّجُودِ فَمَهْمَا أَسْبِقْكُمْ بِهِ إِذَا رَكَعْتُ تُدْرِكُونِي بِهِ إِذَا رَفَعْتُ وَمَهْمَا أَسْبِقْكُمْ بِهِ إِذَا سَجَدْتُ تُدْرِكُونِي بِهِ إِذَا رَفَعْتُ إِنِّي قَدْ بَدَّنْتُ
