The Repentance - 9:103
Take alms from their money to purify them and glorify them, and encourage them and support them, for your support pleases them. Allah is All-Hearing, All-Knowing.
What is meant by the exaltation of those who give alms?
The Repentance/9:99
Among the Arabs are those who believe in Allah and the Last Day. And they consider what they spend as a means to draw near to Allah and support for the messenger. Indeed it is for them a means of approach. Allah will admit them into His mercy. Allah is Forgiving, Merciful.
وَمِنَ الْاَعْرَابِ مَنْ يُؤْمِنُ بِاللّٰهِ وَالْيَوْمِ الْاٰخِرِ وَيَتَّخِذُ مَا يُنْفِقُ قُرُبَاتٍ عِنْدَ اللّٰهِ وَصَلَوَاتِ الرَّسُولِۜ اَلَٓا اِنَّهَا قُرْبَةٌ لَهُمْۜ سَيُدْخِلُهُمُ اللّٰهُ ف۪ي رَحْمَتِه۪ۜ اِنَّ اللّٰهَ غَفُورٌ رَح۪يمٌ۟
