Jabir ibn Abdullah reported: Mu’adh ibn Jabal used to pray with the Prophet, peace and blessings be upon him. Then, he returned to his people and led them in prayer. Mu’adh prayed the evening prayer and recited Surat al-Baqarah, until a man left the prayer, and Mu’adh was critical of him. The news reached the Prophet and he said three times, “You put them to trial!” The Prophet ordered him to recite two medium chapters from the end of the Quran.

عن جَابِر بْن عَبْدِ اللَّهِ قَالَ كَانَ مُعَاذُ بْنُ جَبَلٍ يُصَلِّي مَعَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ثُمَّ يَرْجِعُ فَيَؤُمُّ قَوْمَهُ فَصَلَّى الْعِشَاءَ فَقَرَأَ بِالْبَقَرَةِ فَانْصَرَفَ الرَّجُلُ فَكَأَنَّ مُعَاذًا تَنَاوَلَ مِنْهُ فَبَلَغَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ فَتَّانٌ فَتَّانٌ فَتَّانٌ ثَلَاثَ مِرَارٍ وَأَمَرَهُ بِسُورَتَيْنِ مِنْ أَوْسَطِ الْمُفَصَّلِ
