Volume 4, Book 56, Number 756:
Narrated ‘Abdullah bin Ka’b:
I heard Ka’b bin Malik 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.”
