صحیح مسلم · Hadith 1042

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 ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) and informed him of what Mu'adh had said. Upon this the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) 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).
