At-Tawbah 9:99

وَمِنَ ٱلۡأَعۡرَابِ مَن يُؤۡمِنُ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ وَيَتَّخِذُ مَا يُنفِقُ قُرُبَٰتٍ عِندَ ٱللَّهِ وَصَلَوَٰتِ ٱلرَّسُولِۚ أَلَآ إِنَّهَا قُرۡبَةٞ لَّهُمۡۚ سَيُدۡخِلُهُمُ ٱللَّهُ فِي رَحۡمَتِهِۦٓۚ إِنَّ ٱللَّهَ غَفُورٞ رَّحِيمٞ 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
