Jabir. b. Samura said:
I saw the Prophet on a cloudless[*] night and began to look at God's messenger and at the moon. He was wearing a red robe, and he appeared more beautiful than the moon to me.
*Lisan al-'arab, 19, 115, gives this meaning adding that some say it means `moonlit' and that some say it is a night when the moon shines all night. The word is idhiyan.
Tirmidhi and Darimi transmitted it.
