﴿ ۞ لَّيْسَ عَلَيْكَ هُدَىٰهُمْ وَلَٰكِنَّ ٱللَّهَ يَهْدِى مَن يَشَآءُ ۗ وَمَا تُنفِقُوا۟ مِنْ خَيْرٍۢ فَلِأَنفُسِكُمْ ۚ وَمَا تُنفِقُونَ إِلَّا ٱبْتِغَآءَ وَجْهِ ٱللَّهِ ۚ وَمَا تُنفِقُوا۟ مِنْ خَيْرٍۢ يُوَفَّ إِلَيْكُمْ وَأَنتُمْ لَا تُظْلَمُونَ ﴾

“It is not for thee [O Prophet] to make people follow the right path, since it is God [alone] who guides whom He wills. And whatever good you may spend on others is for your own good, provided that you spend only out of a longing for God's countenance: for, whatever good you may spend will be repaid unto you in full, and you shall not be wronged.”
