Sura al-Tawbah 9:103

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

khudh min amwālihim ṣadaqatan tuṭahhiruhum wa-tuzakkīhim bihā wa-ṣalli ʿalayhim inna ṣalātaka sakanun lahum wallāhu samīʿun ʿalīmun

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.
