سنن النسائي

It was narrated that Jabir said: "Mu'adh bin Jabal led his companions in praying Isha' and he made it lengthy. A man left, and Mu'adh was told about that, and he said: 'He is a hypocrite.' When news of that reached the man, he went to the Prophet (ﷺ) and told him what Mu'adh had said. The Prophet (ﷺ) said to him: 'Do you want to be a cause of hardship, O Mu'adh? When you lead the people in prayer, recite 'By the sun and its brightness' and 'Glorify the Name of your Lord, the Most High' and 'By the night as it envelops'and 'Read! In the Name of your Lord.'"
