But some of the desert Arabs believe in Allah and the Last Day, and look on their payments as pious gifts bringing them nearer to Allah and obtaining the prayers of the Messenger. Aye, indeed they bring them nearer (to Him): soon will Allah admit them to His Mercy: for Allah is Oft-forgiving, Most Merciful.
Compared to :
وَمِنَ الْأَعْرَابِ مَن يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَيَتَّخِذُ مَا يُنفِقُ قُرُبَاتٍ عِندَ اللَّهِ وَصَلَوَاتِ الرَّسُولِ ۚ أَلَا إِنَّهَا قُرْبَةٌ لَّهُمْ ۚ سَيُدْخِلُهُمُ اللَّهُ فِي رَحْمَتِهِ ۗ إِنَّ اللَّهَ غَفُورٌ رَّحِيمٌ
