Sulayman bin Dawud al-Khawlani narrates: I heard Umar bin Abd al-Aziz say to Abu Burdah: Narrate to us a hadith in which there is no other intermediary between you and your father. So Abu Burdah said: I heard my father (that is, Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him)) say: I heard the Prophet (peace and blessings be upon him) say: "My Ummah is a sanctified, blessed Ummah shown mercy; there will be no punishment upon them on the Day of Resurrection; their punishment will be in this world, among themselves, through trials (fitan)."
Al-Tabarani recorded it with two chains; one of them contains a man named al-Qasim, a resident of Hims, whom I do not know. The narrators of this report are the narrators of the Sahih, except for Amr bin Qays al-Sakuni, and he is thiqah (trustworthy).
