Abdullah bin Umar reported,

We used to speak about the Farewell Pilgrimage while the Prophet ﷺ was among us, though we did not know what the Farewell Pilgrimage was. He praised Allah and extolled Him, then mentioned the Messiah Dajjal and spoke at length about him. He said, "Allah never sent a prophet but that he warned his nation about him. Nuh warned of him, and the prophets after him. He will appear among you, and whatever is hidden from you about him, this much will not be hidden from you, that your Lord is not as he appears to be." He said this three times. "Your Lord is not one-eyed, but he is one-eyed in his right eye, as though his eye were a floating grape."

حدثنا يحيى بن سليمان قال أخبرني ابن وهب قال حدثني عمر بن محمد أن أباه حدثه

عن ابن عمر رضي الله عنهما قال

كنا نتحدث بحجة الوداع والنبي ﷺ بين أظهرنا ولا ندري ما حجة الوداع فحمد الله وأثنى عليه ثم ذكر المسيح الدجال فأطنب في ذكره وقال ما بعث الله من نبي إلا أنذر أمته أنذره نوح والنبيون من بعده وإنه يخرج فيكم فما خفي عليكم من شأنه فليس يخفى عليكم أن ربكم ليس على ما يخفى عليكم ثلاثا إن ربكم ليس بأعور وإنه أعور عين اليمنى كأن عينه عنبة طافية
