The Messenger of Allah ﷺ said, "While I was asleep, I saw myself circumambulating the Kaabah. Suddenly there appeared a man of brown complexion with straight hair, walking between two men, with water dripping from his head.I asked, 'Who is this?'They said, 'The son of Mary.'Then I turned and saw a ruddy, heavily built man with curly hair, blind in his right eye, his eye looking like a floating grape.I asked, 'Who is this?'They said, 'This is the Dajjal. The person who most resembles him is Ibn Qatan.'"Ibn Qatan was a man from Banu Mustaliq of Khuza.
قال رسول الله ﷺ: بينما أنا نائم رأيتني أطوف بالكعبة، فإذا رجل آدم سبط الشعر، بين رجلين، ينطف رأسه ماء، فقلت: من هذا؟ قالوا: ابن مريم، فذهبت ألتفت فإذا رجل أحمر جسيم جعد الرأس، أعور العين اليمنى كأن عنبه طافية، قلت: من هذا؟ قالوا: هذا الدجال. أقرب الناس به شبها ابن قطن. وابن قطن رجل من بني المصطلق من خزاعة.
Bukhari narrated it in the Book of Interpretation of Dreams (7026), and Muslim in the Book of Faith (216, 275), both through the route of Salim, from Ibn Umar, who related it. The wording is Bukhari's.
