The Messenger of Allah ﷺ said, "I know more about what is with the Dajjal than he himself does. He will have two flowing rivers with him. One appears to the eye as white water, and the other appears to the eye as a blazing fire. If anyone of you encounters him, let him go to the river he sees as fire, close his eyes, lower his head, and drink from it, for it is actually cool water. The Dajjal's eye is wiped out, with a thick film over it, and between his eyes is written 'disbeliever,' which every believer can read, whether literate or illiterate."
حدثنا أبو بكر بن أبي شيبة حدثنا يزيد بن هارون عن أبي مالك الأشجعي عن ربعي بن حراش
قال رسول الله ﷺ لأنا أعلم بما مع الدجال منه معه نهران يجريان أحدهما رأي العين ماء أبيض والآخر رأي العين نار تأجج فإما أدركن أحد فليأت النهر الذي يراه نارا وليغمض ثم ليطأطئ رأسه فيشرب منه فإنه ماء بارد وإن الدجال ممسوح العين عليها ظفرة غليظة مكتوب بين عينيه كافر يقرؤه كل مؤمن كاتب وغير كاتب
