Abu Qilabah narrates: In Madinah I saw a man around whom people were gathering, and he was saying that the Prophet (peace and blessings be upon him) said: He was one of the Companions of the Prophet (peace and blessings be upon him). The narrator says: I heard him say that (the Prophet (peace and blessings be upon him) said:) "After you there will be the misleading great liar, on the back of whose head there will be locks of curly hair, and he will say: 'I am your Lord.' Whoever says: 'You are not our Lord; rather our Lord is Allah Almighty; in Him we have put our trust and to Him we turn, and we seek refuge in Allah from the one who commits shirk,' the Dajjal will have no power over him."
Ahmad recorded it, and its narrators are the narrators of the Sahih.
