Mukhtasar Bukhari

Narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) used to pray (the Isha) prayer with the Prophet (peace and blessings of Allah be upon him), and then would return and lead his own people in prayer. (On one occasion) he led the Isha prayer and recited Surah Al-Baqarah. A man (broke his prayer and) left, which greatly upset Sayyiduna Mu'adh (may Allah be pleased with him). This news reached the Prophet (peace and blessings of Allah be upon him), so he said to Mu'adh (may Allah be pleased with him) three times: "Fattan, Fattan, Fattan" (one who causes trouble), or he said: "Faatin, Faatin, Faatin" (one who creates discord). And the Prophet (peace and blessings of Allah be upon him) instructed Mu'adh (may Allah be pleased with him) to recite two short surahs from the Mufassal.
