Sayyiduna Jabir (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "When you see my Ummah afraid of the oppressor, (afraid) to say to him: 'You are an oppressor,' then the time of their farewell will have come."
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains Sinan bin Harun, who is da'if (weak), though al-Tirmidhi graded his hadith hasan (good); the rest of its narrators are thiqat (trustworthy).
