Sahih Muslim: Book 4, Hadith 202

Jabir reported that Mu’adh b. Jabal used to pray with the Apostle (ﷺ), then came and led his people in prayer. One night he said the night prayer with the Messenger of Allah (ﷺ). He then came to his people and led them in prayer beginning with Surat al-Baqara. A man turned aside, pronounced the taslim (salutation for concluding the prayer), then prayed alone and departed. The people said to him: Have you become a hypocrite, so and so? He said: I swear by Allah that I have not, but I will certainly go to Allah’s Messenger (ﷺ) and will inform (him) about this. He then came to the Messenger of Allah (ﷺ) and said: Messenger of Allah, we look after camels used for watering and work by day. Mu’adh said the night prayer with you. He then came and began with Surat al-Baqara. Allah’s Messenger (ﷺ) then turned to Mu’adh and said: Are you there to (put the people) to trial? Recite such and recite such (and such a surah). It is transmitted on the authority of Jabir, as told by Sufyan, that he (the Holy Prophet) had said: “By the sun and its morning brightness” (Surah xci), “By brightness” (Surah xciii), “By the night when it spreads” (Surah xcii), and “Glorify the name of thy most high Lord” (Surah lxxxii).
