Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) was leading the people of his tribe in prayer. Meanwhile a man named Haram entered the mosque; he intended to water his date palms, and he came into the mosque to pray with the people. When he saw that Sayyiduna Mu'adh (may Allah be pleased with him) was lengthening the prayer, he offered a short prayer and went off to water his date palms. When Sayyiduna Mu'adh (may Allah be pleased with him) completed the prayer, he was told: "Sayyiduna Haram (may Allah be pleased with him) came into the mosque, and when he saw that you were lengthening the prayer, he offered a short prayer and went off to water his date orchard." Sayyiduna Mu'adh (may Allah be pleased with him) said: "He is a hypocrite. Did he hurry through his prayer for the sake of watering date palms?" The narrator says: Sayyiduna Haram (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) while Sayyiduna Mu'adh (may Allah be pleased with him) was with the Prophet (peace and blessings be upon him). Sayyiduna Haram (may Allah be pleased with him) said: "O Prophet of Allah, I intended to water my date orchard. I entered the mosque to pray with the people, and when he lengthened the prayer, I offered a short prayer and went to my date orchard to water it. He claims that I am a hypocrite." The Prophet (peace and blessings be upon him) turned to Sayyiduna Mu'adh (may Allah be pleased with him) and said: "Are you one who puts people to trial? Do not lead them in long prayers. Recite Surah al-A'la, Surah al-Shams and other surahs like them."
Ahmad and al-Bazzar recorded it, and the narrators of Ahmad are the narrators of the Sahih.
