۞ 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
The guiding of them is not thy duty (O Muhammad), but Allah guideth whom He will. And whatsoever good thing ye spend, it is for yourselves, when ye spend not save in search of Allah's Countenance; and whatsoever good thing ye spend, it will be repaid to you in full, and ye will not be wronged.
Surah Al-Baqara(2:272)
