Muʿadh bin Jabal used to pray with the Prophet ﷺ and then go to lead his people in prayer. Once he led the people in prayer and recited Surat-al-Baqara. A man left (the row of the praying people) and offered (light) prayer (separately) and went away. When Muʿadh came to know about it, he said. "He (that man) is a hypocrite." Later that man heard what Muʿadh said about him, so he came to the Prophet and said, "O Messenger of Allah ﷺ! We are people who work with our own hands and irrigate (our farms) with our camels. Last night Muʿadh led us in the (night) prayer and he recited Sura-al-Baqara, so I offered my prayer separately, and because of that, he accused me of being a hypocrite." The Prophet called Muʿadh and said thrice, "O Muʿadh! You are putting the people to trials? Recite 'Washshamsi wad-uhaha' (91) or'Sabbih isma Rabbi ka-l-A'la' (87) or the like."  

أَنَّ مُعَاذَ بْنَ جَبَلٍ ؓ كَانَ يُصَلِّي مَعَ النَّبِيِّ ﷺ ثُمَّ يَأْتِي قَوْمَهُ فَيُصَلِّي بِهِمُ الصَّلاَةَ فَقَرَأَ بِهِمُ الْبَقَرَةَ قَالَ فَتَجَوَّزَ رَجُلٌ فَصَلَّى صَلاَةً خَفِيفَةً فَبَلَغَ ذَلِكَ مُعَاذًا فَقَالَ إِنَّهُ مُنَافِقٌ فَبَلَغَ ذَلِكَ الرَّجُلَ فَأَتَى النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّا قَوْمٌ نَعْمَلُ بِأَيْدِينَا وَنَسْقِي بِنَوَاضِحِنَا وَإِنَّ مُعَاذًا صَلَّى بِنَا الْبَارِحَةَ فَقَرَأَ الْبَقَرَةَ فَتَجَوَّزْتُ فَزَعَمَ أَنِّي مُنَافِقٌ فَقَالَ النَّبِيُّ ﷺ يَا مُعَاذُ أَفَتَّانٌ أَنْتَ ثَلاَثًا اقْرَأْ {وَالشَّمْسِ وَضُحَاهَا} وَ{سَبِّحِ اسْمَ رَبِّكَ الأَعْلَى} وَنَحْوَهَا
