On leading people for longer than they can take
Muʿādh led a long night prayer and a man left and prayed alone.
أَتُرِيدُ أَنْ تَكُونَ فَتَّانًا يَا مُعَاذُ إِذَا أَمَمْتَ النَّاسَ فَاقْرَأْ بِالشَّمْسِ وَضُحَاهَا . وَسَبِّحِ اسْمَ رَبِّكَ الأَعْلَى . وَاقْرَأْ بِاسْمِ رَبِّكَ . وَاللَّيْلِ إِذَا يَغْشَى
Are you one who puts people to trial, Muʿādh? When you lead people in prayer, recite the sun and its brightness, and glorify the name of your Lord the Most High, and read in the name of your Lord, and by the night when it covers.
The man who left was criticised by others and defended by the Prophet ﷺ, who then corrected the imam instead.
The full narration
Jabir reported:'Mu'adh b. Jabal al-Ansari led his companions in the night prayer and prolonged it for them. A person amongst us said prayer (after having separated himself from the congregation). Mu'adh was informed of this, and he remarked that he was a hypocrite. When it (the remark) was conveyed to the man, he went to the Messenger of Allah (ﷺ) and informed him of what Mu'adh had said. Upon this the Messenger of Allah (ﷺ) said to him: Mu'adh, do you want to become a person putting (people) to trial? When you lead people in prayer, recite:" By the Sun and its morning brightness" (Surat ash-Shams)," Glorify the name of thy most high Lord" (Surat al-A`la) and" Read in the name of Lord" (Surat al-`Alaq), and" By the night when it spreads" (Surat al-Lail)
