Narrated Jabir bin `Abdullah: Mu`adh bin Jabal used to pray with the Prophet and then go to lead his people in prayer. Once he led the people in prayer and recited Surat-al-Baqara. A man left (the row of the praying people) and offered (light) prayer (separately) and went away. When Mu`adh came to know about it, he said. He (that man) is a hypocrite. Later that man heard what Mu`adh said about him, so he came to the Prophet and said, O Allah's Apostle! We are people who work with our own hands and irrigate (our farms) with our camels. Last night Mu`adh led us in the (night) prayer and he recited Sura-al-Baqara, so I offered my prayer separately, and because of that, he accused me of being a hypocrite. The Prophet called Mu`adh and said thrice, O Mu`adh! You are putting the people to trials? Recite 'Washshamsi wad-uhaha' (91) or'Sabbih isma Rabbi ka-l-A'la' (87) or the like.
