و حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا لَيْثٌ قَالَ ح و حَدَّثَنَا ابْنُ رُمْحٍ أَخْبَرَنَا اللَّيْثُ عَنْ أَبِي الزُّبَيْرِ عَنْ جَابِرٍ أَنَّهُ قَالَ صَلَّى مُعَاذُ بْنُ جَبَلٍ الْأَنْصَارِيُّ لِأَصْحَابِهِ الْعِشَاءَ فَطَوَّلَ عَلَيْهِمْ فَانْصَرَفَ رَجُلٌ مِنَّا فَصَلَّى فَأُخْبِرَ مُعَاذٌ عَنْهُ فَقَالَ إِنَّهُ مُنَافِقٌ فَلَمَّا بَلَغَ ذَلِكَ الرَّجُلَ دَخَلَ عَلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَخْبَرَهُ مَا قَالَ مُعَاذٌ فَقَالَ لَهُ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَتُرِيدُ أَنْ تَكُونَ فَتَّانًا يَا مُعَاذُ إِذَا أَمَمْتَ النَّاسَ فَاقْرَأْ بِالشَّمْسِ وَضُحَاهَا وَسَبِّحْ اسْمَ رَبِّكَ الْأَعْلَى وَاقْرَأْ بِاسْمِ رَبِّكَ وَاللَّيْلِ إِذَا يَغْشَى

It was narrated that Jabir said: "Mu'adh bin Jabal Al-Ansari led his companions in praying 'Isha' and he made it long for them. A man went away and prayed (separately), and Mu'adh was told about that, and said: 'He is a hypocrite.' When news of that reached the man, he went to the Messenger of Allah (s.a.w) and told him what Mu'adh had said. The Prophet (s.a.w) said to him: 'Do you want to cause Fintah, O Mu'adh? When you lead the people in prayer, recite: "By the sun and its brightness", "Glorify the Name of your Lord, the Most High" "Read! In the Name of your Lord" and: "By the night as it envelops."
