At-Tawbah 9:99

وَمِنَ ٱلۡأَعۡرَابِ مَن يُؤۡمِنُ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ وَيَتَّخِذُ مَا يُنفِقُ قُرُبَٰتٍ عِندَ ٱللَّهِ وَصَلَوَٰتِ ٱلرَّسُولِۚ أَلَآ إِنَّهَا قُرۡبَةࣱ لَّهُمۡۚ سَيُدۡخِلُهُمُ ٱللَّهُ فِي رَحۡمَتِهِۦٓۚ إِنَّ ٱللَّهَ غَفُورࣱ رَّحِيمࣱ‏۝٩٩

99. But among the bedouins are some who believe in Allah and the Last Day and consider what they spend as means of nearness to Allah and of [obtaining] invocations of the Messenger. Unquestionably, it is a means of nearness for them. Allah will admit them to His mercy. Indeed, Allah is Forgiving and Merciful
