The Messenger of Allah ﷺ said, "I know more about what Dajjal will have with him than he himself does. He will have two flowing rivers with him. One will appear to the eye as white water, and the other will appear to the eye as blazing fire. If anyone reaches that time, let him go to the river that looks like fire, close his eyes, lower his head, and drink from it, for it will actually be cool water. Dajjal's eye will be wiped out, covered by a thick membrane, and between his eyes will be written 'Disbeliever,' which every believer will read, whether literate or illiterate."
قال رسول الله ﷺ: لأنا أعلم بما مع الدجال منه، معه نهران يجريان: أحدهما رأى العين، ماء أبيض، والآخر رأى 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.
