Hadith 4:462

Narrated Ibn Abbas:

The Prophet said, "On the night of my Ascent to the Heaven, I saw Moses who was a tall brown curly-haired man as if he was one of the men of Shan'awa tribe, and I saw Jesus, a man of medium height and moderate complexion inclined to the red and white colors and of lank hair. I also saw Malik, the gate-keeper of the (Hell) Fire and Ad-Dajjal amongst the signs which Allah showed me." (The Prophet then recited the Holy Verse): "So be not you in doubt of meeting him' when you met Moses during the night of Mi'raj over the heavens" (32.23)
