Read and reflect on verse 279 from Surah Al-Baqara: 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...
۞ لَيْسَ عَلَيْكَ هُدَاهُمْ وَلَٰكِنَّ اللَّهَ يَهْدِي مَنْ يَشَاءُ ۗ وَمَا تُنْفِقُوا مِنْ خَيْرٍ فَلِأَنْفُسِكُمْ ۚ وَمَا تُنْفِقُونَ إِلَّا ابْتِغَاءَ وَجْهِ اللَّهِ ۚ وَمَا تُنْفِقُوا مِنْ خَيْرٍ يُوَفَّ إِلَيْكُمْ وَأَنْتُمْ 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.
