“Mu’adh bin Jabal Al-Ansari led his companions in the ‘Isha’ prayer and he made it long. A man among us went away and prayed by himself. Mu’adh was told about that and he said: ‘He is a hypocrite.’ When the man heard about that, he went to the Messenger of Allah (ﷺ) and told him what Mu’adh had said to him. The Prophet (ﷺ) said: ‘Do you want to be a cause of Fitnah (trial, tribulation), O Mu’adh? When you lead the people in prayer, recite “By the sun and its brightness,”[Ash-Shams 91] and “Glorify the Name of your Lord the Most High,” [Al-A’la 87] and “By the night as it envelopes,” [Al-Lail 92] and “Recite in the Name of your Lord.’”[Al-‘Alaq]
