Silsilat al-Ahadith al-Sahihah

Abu Qilabah says: I saw a man in Madinah Munawwarah, people were circling around him and he was saying, "The Messenger of Allah (peace and blessings be upon him) said, the Messenger of Allah (peace and blessings be upon him) said." That man was a companion of the Messenger, and I heard him saying: "After you, there will arise an extremely deceitful and misguided man, his hair will be curly (or twisted), he will say: I am your Lord. Whoever answers him like this: You are not our Lord, our Lord is Allah, we have placed our trust in Him, to Him we turn, and we seek Allah's protection from your evil—then he will have no power over him."
