Surah At-Taubah (The Repentance), Verse 103

خُذْ مِنْ اَمْوَالِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكِّیْهِمْ بِهَا وَصَلِّ عَلَیْهِمْ اِنَّ صَلٰوتَكَ سَكَنٌ لَّهُمْ وَاللّٰهُ سَمِیْعٌ عَلِیْمٌ ۟

Khuz min amwaalihim sadaqatan tutahhiruhum wa tuzakkeehim bihaa wa salli 'alaihim inna salaataka sakanul lahum; wallaahu Samee'un 'Aleem

“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.”
