The Messenger of Allah ﷺ said, "I know more about what is with Dajjal than Dajjal himself. He has with him two flowing rivers. One appears to the eye as white water, and the other appears to the eye as a blazing fire. If any of you encounters him, let him go to the river that he sees as fire, close his eyes, lower his head, and drink from it, for it is in fact cool water. Dajjal's left 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 not."
حدثنا يزيد بن هارون حدثنا أبو مالك سعيد بن طارق الأشجعي حدثني ربعي بن حراش
قال رسول الله ﷺ لأنا أعلم بما مع الدجال من الدجال معه نهران يجريان أحدهما رأي العين ماء أبيض والآخر رأي العين نار تأجج فإما أدركن أحدا منكم فليأت النهر الذي يراه نارا وليغمض ثم ليطأطئ رأسه فليشرب فإنه ماء بارد وإن الدجال ممسوح العين اليسرى عليها ظفرة غليظة وفيه مكتوب بين عينيه كافر يقرؤه كل مؤمن كاتب وغير كاتب
