At-Taubah - 9:103

خُذْ مِنْ أَمْوَالِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكِّيهِم بِهَا وَصَلِّ عَلَيْهِمْ إِنَّ صَلاَتَكَ سَكَنٌ لَّهُمْ وَاللّهُ سَمِيعٌ عَلِيمٌ
[9:103]
Take alms out of their property, you would cleanse them and purify them thereby, and pray for them; surely your prayer is a relief to them; and Allah is Hearing, Knowing.
Of their goods, take alms, that so thou mightest purify and sanctify them; and pray on their behalf. Verily thy prayers are a source of security for them: And Allah is One Who heareth and knoweth.
Take alms of their wealth, wherewith thou mayst purify them and mayst make them grow, and pray for them. Lo! thy prayer is an assuagement for them. Allah is Hearer, Knower.
