Surah At-Tawbah, ayah 103

9:103

خُذۡ مِنۡ أَمۡوَٰلِهِمۡ صَدَقَةٗ تُطَهِّرُهُمۡ وَتُزَكِّيهِم بِهَا وَصَلِّ عَلَيۡهِمۡۖ إِنَّ صَلَوٰتَكَ سَكَنٞ لَّهُمۡۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ ١٠٣

Khudh min amwālihim sadaqatan tutahhiruhum watuzakkīhim bihā wasalli 'alayhim inna salawātaka sakanul lahum wallāhu samī'un 'alīm

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.
