Hadith 790:61
Yahya ibn Sa'id narrated to us, Hisham ibn Hassan narrated to us, Humayd ibn Hilal narrated to us, from Abu al-Dahma', from 'Imran ibn Husayn, from the Prophet, peace and blessings of Allah be upon him, who said: "Whoever hears of the Dajjal, let him keep away from him. Whoever hears of the Dajjal, let him keep away from him. Whoever hears of the Dajjal, let him keep away from him. For a man will come to him while he thinks that he is a believer, and he will continue to follow him due to the doubts he possesses until he follows him."
حدثنا يحيى بن سعيد، حدثنا هشام بن حسان، حدثنا حميد بن هلال، عن أبي الدهماء، عن عمران بن حصين، عن النبي صلى الله عليه وسلم قال: " من سمع بالدجال فلينأ منه؛ من سمع بالدجال، فلينأ منه من سمع بالدجال، فلينأ منه، فإن الرجل يأتيه وهو يحسب أنه مؤمن، فلا يزال به لما معه من الشبه حتى يتبعه "
