«ما بعث الله من نبي إلا أنذر أمته الدجال أنذره نوح والنبيون من بعده وإنه يخرج فيكم فما خفي عليكم من شأنه فليس يخفى عليكم أن ربكم ليس بأعور وإنه أعور العين اليمنى كأن عينه عنبة طافية ألا إن الله حرم عليكم دماءكم وأموالكم كحرمة يومكم هذا في بلدكم هذا في شهركم هذا ألا هل بلغت: اللهم اشهد ثلاثا ويحكم! انظروا لا ترجعوا بعدي كفارا يضرب بعضكم رقاب بعض»
The Prophet (peace and blessings be upon him) said:
"Allah did not send any prophet except that he warned his nation about the Dajjal. Nuh and all the prophets after him warned about him. He will certainly emerge among you, and whatever of his affair may remain hidden from you, it will not be hidden from you that your Lord is not one-eyed, whereas the Dajjal will be blind in the right eye, as though his eye were a protruding grape. Listen! Allah has made your blood and your wealth sacred to you just like the sanctity of this day of yours, in this city of yours, in this month of yours. Beware! Have I conveyed the message? O Allah, be witness (he said this three times). Woe to you! Look, do not become disbelievers after me, striking the necks of one another."
