أن عبد الله بن كعب، قال: سمعت كعب بن مالك يحدَّث: حِينَ تَخَلَّفَ عَنْ تَبُوكَ، قَالَ فَلَمَّا سَلَّمْتُ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَهْوَ يَبْرُقُ وَجْهُهُ مِنَ السُّرُورِ، وَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا سُرَّ اسْتَنَارَ وَجْهُهُ، حَتَّى كَأَنَّهُ قِطْعَةُ قَمَرٍ، وَكُنَّا نَعْرِفُ ذَلِكَ مِنْهُ. صحيح البخاري حديث ٣٥٥٦
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 Messenger (peace be upon him) whose face was glittering with happiness, for whenever Allah’s Messenger (peace be upon him) 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.
