خُذ مِن أَموالِهِم صَدَقَةً تُطَهِّرُهُم وَتُزَكّيهِم بِها وَصَلِّ عَلَيهِم ۖ إِنَّ صَلاتَكَ سَكَنٌ لَهُم ۗ وَاللَّهُ سَميعٌ عَليمٌ

Take, [O, Muhammad], from their wealth a charity by which you purify them and cause them increase, and invoke [Allah 's blessings] upon them. Indeed, your invocations are reassurance for them. And Allah is Hearing and Knowing.
