اَلَّذِيْنَ يُنْفِقُوْنَ اَمْوَالَهُمْ فِيْ سَبِيْلِ اللّٰهِ ثُمَّ لَا يُتْبِعُوْنَ مَآ اَنْفَقُوْا مَنًّا وَّلَآ اَذًىۙ لَّهُمْ اَجْرُهُمْ عِنْدَ رَبِّهِمْۚ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُوْنَ ( البقرة: ٢٦٢ )
Allazeena yunfiqoona amwaalahum fee sabeelillaahi summa laa yutbi'oona maaa anfaqoo mannanw wa laaa azal lahum ajruhum 'inda Rabbihim; wa laa khawfun 'alaihim wa laa hum yahzanoon (al-Baq̈arah 2:262)
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. (Al-Baqarah  : 262)
1 Mufti Taqi Usmani
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.
