It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to us: "I warn you of seven trials that will occur after me: a trial that will arise from Madinah, a trial in Makkah, a trial that will come from Yemen, a trial that will come from Sham, a trial that will come from the east, a trial that will come from the west, and a trial that will arise from the heart of Sham, and that is the trial of the Sufyani." Ibn Mas'ud (may Allah be pleased with him) said: "Among you will be those who will witness the beginning of these trials, and among this Ummah will be those who will witness their end." Al-Walid bin Ayyash (the narrator) said: The trial of Madinah was from the side of Talhah and al-Zubayr, the trial of Makkah was the trial of Abdullah bin al-Zubayr, the trial of Sham was from the side of Banu Umayyah, and the trial of the east was from the side of these people. This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
