Quran 9:99 At-Tawbah, ayah 99 of 129

وَمِنَ ٱلْأَعْرَابِ مَن يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ وَيَتَّخِذُ مَا يُنفِقُ قُرُبَـٰتٍ عِندَ ٱللَّهِ وَصَلَوَٰتِ ٱلرَّسُولِ ۚ أَلَآ إِنَّهَا قُرْبَةٌ لَّهُمْ ۚ سَيُدْخِلُهُمُ ٱللَّهُ فِى رَحْمَتِهِۦٓ ۗ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ ۝٩٩

9:99 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.
