Mishkat al-Masabih 29 Excellent Qualities and Description of the Prophet كتاب الفضائل والشمائل 54

وَعَنْ جَابِرِ بْنِ سَمُرَةَ قَالَ: رَأَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي لَيْلَةٍ إِضْحِيَانٍ فَجَعَلْتُ أَنْظُرُ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَإِلَى الْقَمَرِ وَعَلَيْهِ حُلَّةٌ حَمْرَاءُ فَإِذَا هُوَ أَحْسَنُ عِنْدِي مِنَ الْقَمَرِ. رَوَاهُ التِّرْمِذِيّ والدارمي

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.
