وَمِنَ ٱلْأَعْرَابِ مَن يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ وَيَتَّخِذُ مَا يُنفِقُ قُرُبَٰتٍ عِندَ ٱللَّهِ وَصَلَوَٰتِ ٱلرَّسُولِ ۚ أَلَآ إِنَّهَا قُرْبَةٌۭ لَّهُمْ ۚ سَيُدْخِلُهُمُ ٱللَّهُ فِى رَحْمَتِهِۦٓ ۗ إِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌۭ
And of the wandering Arabs there is he who believeth in Allah and the Last Day, and taketh that which he expendeth and also the prayers of the messenger as acceptable offerings in the sight of Allah. Lo! verily it is an acceptable offering for them. Allah will bring them into His mercy. Lo! Allah is Forgiving, Merciful.

Virtues and Merits of the Prophet (pbuh) and his Companions
Chapter: The description of the Prophet (saws)
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 (ﷺ) whose face was glittering with happiness, for whenever Allah's Messenger (ﷺ) 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."
