خُذْ مِنْ أَمْوَٰلِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكِّيهِم بِهَا وَصَلِّ عَلَيْهِمْ ۖ إِنَّ صَلَوٰتَكَ سَكَنٌ لَّهُمْ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ

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

At-Tawbah 103
