Al-Baqarah 2:262

Allatheena yunfiqoona amwalahumfee sabeeli Allahi thumma la yutbiAAoona maanfaqoo mannan wala athan lahum ajruhum AAindarabbihim wala khawfun AAalayhim wala hum yahzanoon

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.

Those who spend their wealth in the way of Allah, then do not make their spending followed by boasting about favour, or with causing hurt,- they have their reward with their Lord and there is no fear for them nor shall they grieve.
