“A man came to the Prophet ﷺ and said: ‘O Messenger of Allah! I stay behind and do not perform the morning prayer (in congregation) because of so-and-so, for he makes it too long for us.’ I never saw the Messenger of Allah ﷺ preaching with such anger as he did that day. He said; ‘O people! There are among you those who repel others. Whoever among you leads others in prayer, let him keep it short, for among them are those who are weak and elderly, and those who have pressing needs.’” (Using translation from Ibn Mājah 984)   

جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ وَاللَّهِ إِنِّي لَأَتَأَخَّرُ عَنْ صَلَاةِ الْغَدَاةِ مِمَّا يُطِيلُ بِنَا فِيهَا فُلَانٌ فَمَا رَأَيْتُ النَّبِيَّ ﷺ أَشَدَّ غَضَبًا فِي مَوْعِظَةٍ مِنْهُ يَوْمَئِذٍ فَقَالَ «أَيُّهَا النَّاسُ إِنَّ مِنْكُمْ مُنَفِّرِينَ فَمَنْ صَلَّى بِالنَّاسِ فَلْيَتَجَوَّزْ فَإِنَّ فِيهِمُ الْكَبِيرَ وَالضَّعِيفَ وَذَا الْحَاجَةِ»  

[Machine] I heard Anas say that the Prophet ﷺ used to perform the most secretive and concealed prayers among the people.  

سَمِعْتُ أَنَسًا يَقُولُ كَانَ النَّبِيُّ ﷺ «أَخَفَّ النَّاسِ صَلَاةً فِي تَمَامٍ»
