Al-Baqarah 2:262

ٱلَّذِينَ يُنفِقُونَ أَمۡوَٰلَهُمۡ فِي سَبِيلِ ٱللَّهِ ثُمَّ لَا يُتۡبِعُونَ مَآ أَنفَقُواْ مَنّٗا وَلَآ أَذٗى لَّهُمۡ أَجۡرُهُمۡ عِندَ رَبِّهِمۡ وَلَا خَوۡفٌ عَلَيۡهِمۡ وَلَا هُمۡ يَحۡزَنُونَ 262

Those who spend their wealth in the way of Allah 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
