'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-Aʿla) and" Read in the name of Lord" (Surat al-ʿAlaq), and" By the night when it spreads" (Surat al-Lail).
إِنَّهُ مُنَافِقٌ فَلَمَّا بَلَغَ ذَلِكَ الرَّجُلَ دَخَلَ عَلَى رَسُولِ اللَّهِ ﷺ فَأَخْبَرَهُ مَا قَالَ مُعَاذٌ فَقَالَ لَهُ النَّبِيُّ ﷺ أَتُرِيدُ أَنْ تَكُونَ فَتَّانًا يَا مُعَاذُ إِذَا أَمَمْتَ النَّاسَ فَاقْرَأْ بِالشَّمْسِ وَضُحَاهَا وَسَبِّحِ اسْمَ رَبِّكَ الأَعْلَى وَاقْرَأْ بِاسْمِ رَبِّكَ وَاللَّيْلِ إِذَا يَغْشَى
