sincerity in charity

ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمْ فِى سَبِيلِ ٱللَّهِ ثُمَّ لَا يُتْبِعُونَ مَآ أَنفَقُوا۟ مَنًّا وَلَآ أَذًى ۙ لَّهُمْ أَجْرُهُمْ عِندَ رَبِّهِمْ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ

Those who spend their wealth in the way of Allāh and then do not follow up what they have spent with reminders [of it] or [other] injury will have their reward with their Lord, and there will be no fear concerning them, nor will they grieve.

وَلَا يُنفِقُونَ نَفَقَةً صَغِيرَةً وَلَا كَبِيرَةً وَلَا يَقْطَعُونَ وَادِيًا إِلَّا كُتِبَ لَهُمْ لِيَجْزِيَهُمُ ٱللَّهُ أَحْسَنَ مَا كَانُوا۟ يَعْمَلُونَ

Nor do they spend an expenditure, small or large, or cross a valley but that it is registered for them that Allāh may reward them for the best of what they were doing.

وَمَا لِأَحَدٍ عِندَهُۥ مِن نِّعْمَةٍ تُجْزَىٰٓ

And not [giving] for anyone who has [done him] a favor to be rewarded
