لَيۡسَ عَلَيۡكَ هُدٰٮهُمۡ وَلٰـكِنَّ اللّٰهَ يَهۡدِىۡ مَنۡ يَّشَآءُ ؕ وَمَا تُنۡفِقُوۡا مِنۡ خَيۡرٍ فَلِاَنۡفُسِكُمۡؕ وَمَا تُنۡفِقُوۡنَ اِلَّا ابۡتِغَآءَ وَجۡهِ اللّٰهِؕ وَمَا تُنۡفِقُوۡا مِنۡ خَيۡرٍ يُّوَفَّ اِلَيۡكُمۡ وَاَنۡـتُمۡ لَا تُظۡلَمُوۡنَ(البقرة :272)

Not upon you, [O Muhammad], is [responsibility for] their guidance, but Allah guides whom He wills. And whatever good you [believers] spend is for yourselves, and you do not spend except seeking the countenance of Allah . And whatever you spend of good - it will be fully repaid to you, and you will not be wronged.
وَاَعِدُّوۡا لَهُمۡ مَّا اسۡتَطَعۡتُمۡ مِّنۡ قُوَّةٍ وَّمِنۡ رِّبَاطِ الۡخَـيۡلِ تُرۡهِبُوۡنَ بِهٖ عَدُوَّ اللّٰهِ وَعَدُوَّكُمۡ وَاٰخَرِيۡنَ مِنۡ دُوۡنِهِمۡ ۚ لَا تَعۡلَمُوۡنَهُمُ ۚ اَللّٰهُ يَعۡلَمُهُمۡؕ وَمَا تُـنۡفِقُوۡا مِنۡ شَىۡءٍ فِىۡ سَبِيۡلِ اللّٰهِ يُوَفَّ اِلَيۡكُمۡ وَاَنۡـتُمۡ لَا تُظۡلَمُوۡنَ(الأنفال :60)

قُلۡ اِنَّ رَبِّىۡ يَبۡسُطُ الرِّزۡقَ لِمَنۡ يَّشَآءُ مِنۡ عِبَادِهٖ وَيَقۡدِرُ لَهٗ ؕ وَمَاۤ اَنۡفَقۡتُمۡ مِّنۡ شَىۡءٍ فَهُوَ يُخۡلِفُهٗ ۚ وَهُوَ خَيۡرُ الرّٰزِقِيۡنَ(سبإ :39)
