An-Nasa'i recorded a narration from Jabir that Mu`adh prayed a prayer and a man came and joined him in the prayer. Mu`adh made the prayer long, so the man went and prayed (alone) at the side of the Masjid, and then left. When Mu`adh was informed of this he said, "(He is) a hypocrite.'' He (Mu`adh) then informed the Messenger of Allah of what happened. The Prophet then asked the young man (about it) and he replied, "O Messenger of Allah! I came to pray with him, but he made the prayer too long for me. So I left him and prayed at the side of the Masjid. Then I went to feed my she-camel.'' The Messenger of Allah then said,
(Are you causing trouble Mu`adh Why don't you recite (`Glorify the Name of your Lord the Most High'), (`By the sun and its brightness'), (`By the dawn'), (and (`By the night as it envelops'))
In the Name of Allah, the Most Gracious, the Most Merciful
