Sahih Bukhari, 4.756: Narrated Abdullah bin Ka’b R.A:
I heard Ka'b bin Malik R.A talking after his failure to join (the Ghazwa of) Tabuk. He said, "When I greeted Allah's Apostle whose face was glittering with happiness, for whenever Allah's Apostle was happy, his face used to glitter, as if it was a piece of the moon, and we used to recognize it (i.e. his happiness) from his face."

Sahi Bukhari, 4.752: Narrated Abu Ishaq R.A:
Al-Bara R.A was asked, "Was the face of the Prophet (as bright) as a sword?" He said, "No, but (as bright) as a moon."




The Holy Prophet (Allah bless him and give him peace) is the Light of Allah, he is of course a created light. Someone who believes otherwise has made the mistake of the Christians with Jesus (upon whom be peace).



The Prophet (PBUH) also said:

"I was a Prophet while Adam was still between the spirit and the body."

Imam Tirmidhi R.A narrated it and said it hasan sahih, and it is authenticated by al-Hakim 2:609 as sahih, and also narrated by Ibn Abi Shayba in his Musannaf 14:292, and al-Bukhari in his Tarikh 7:374.
