Did the Noble Prophet صلى الله عليه وسلم see the Dajjal?
عن ابن عباس رضى الله عنه عن النبى صلى الله عليه وسلم قال : رأيت ليلة أسري بى موسى رجلا آدم طوالا جعدا كأنه من رجال شنوءة ورأيت عيسى رجلا مربوعا ، مربوع الخلق إلى الحمرة والبياض سبط الرأس ورأيت مالكا خازن النار والدجال فى آيات أراهن الله إياه فلا تكن فى مرية من لقائه
It is narrated from Hazrat Abdullah bin Abbas (may Allah be pleased with them) that the Messenger of Allah (peace be upon him) said, on the night of Mi'raj, I saw Musa (Moses) (peace be upon him). He was wheat-colored, tall, and had curly hair, looking as if he belonged to the tribe of Shanuwa. I also saw Isa (Jesus) (peace be upon him), who was of medium height, medium build, fair-skinned, and had straight hair. I saw the gatekeeper of Hell and I also saw the Dajjal. Among other things, I saw the verses that Allah showed me (mentioned in Surah As-Sajda, verse 23). Therefore, do not have any doubt about the meeting with him (the Prophet Muhammad, peace be upon him).

It is narrated from Hazrat Abdullah bin Umar (may Allah be pleased with them) that the Messenger of Allah (peace be upon him) said: I was sleeping (in a dream) and was performing Tawaf of the Kaaba when I saw a man who was wheat-colored and had straight hair, as if water was dripping from it (I looked at him). I asked, "Who is this?" People told me, "This is Isa bin Maryam (Jesus, son of Mary)." Then I turned and saw a stout man who was red in complexion, had curly hair, and was one-eyed, as if his eye was swollen like a grape. People told me, "This is the Dajjal." His appearance was very similar to that of Abd al-Uzza bin Qatan Khuzai.
