Musannaf Ibn Abi Shaybah 34289 — The virtues of Ali bin Abi Talib

Abu Ubaydah bin al-Hakam al-Azdi (may Allah have mercy on him) narrated a marfu' hadith that the Prophet (peace and blessings be upon him) said to Sayyiduna Ali (may Allah be pleased with him): "You will soon meet with hardship after me." He asked: "O Messenger of Allah (peace and blessings be upon him), will my religion remain safe in it?" He (peace and blessings be upon him) said: "Yes! Your religion will remain safe."
