The Messenger of Allah ﷺ said, "While I was sleeping, I saw myself performing tawaf around the Kaabah. Suddenly I saw a brown-skinned man with straight hair, walking between two men, water dripping from his head.I asked, 'Who is this?'They replied, 'The son of Maryam.'Then I turned and saw a ruddy-complexioned, heavily built man with curly hair, blind in his right eye, his eye looking like a floating grape.I asked, 'Who is this?'They replied, 'This is the Dajjal. The person who resembles him most closely is Ibn Qatan, a man from the tribe of Banu Mustaliq.'"
حدثنا أبو اليمان حدثنا شعيب عن الزهري أخبرني سالم بن عبد الله أن
قال رسول الله ﷺ بينا أنا نائم رأيتني أطوف بالكعبة فإذا رجل آدم سبط الشعر بين رجلين ينطف رأسه ماء فقلت من هذا فقالوا ابن مريم فذهبت ألتفت فإذا رجل أحمر جسيم جعد الرأس أعور عين اليمنى كأن عينه عنبة طافية فقلت من هذا فقالوا الدجال أقرب الناس به شبها ابن قطن رجل من بني المصطلق
Its isnad is sahih, and it is a longer version of 5553, see also 4948. As for "tafiyah," Ibn Athir said, it is the grain that has grown beyond the normal limit of its plant and its usual states, so it stands out from among the rest and rises above them. It has also been said that what is meant is the grain that floats on the surface of water, likening his eye to it.
