Musannaf Ibn Abi Shaybah 32328 — Reports on faith and Islam

Sayyiduna Ali (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said: "There are four things without which a man will never find the taste of faith, until he believes in them with certainty from the heart. They are: believing with certainty that there is no god worthy of worship except Allah, alone, and that I am indeed the Messenger of Allah, whom Allah has sent with the truth; believing with certainty that he will die and will be raised again after death; and accepting from the heart every kind of divine decree."
