9:103
خُذْ مِنْ أَمْوَٰلِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكِّيهِم بِهَا وَصَلِّ عَلَيْهِمْ ۖ إِنَّ صَلَوٰتَكَ سَكَنٌ لَّهُمْ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ
khudh min amwālihim ṣadaqatan tuṭahhiruhum watuzakkīhim bihā waṣalli ʿalayhim inna ṣalataka sakanun lahum wal-lahu samīʿun ʿalīmun
In order to cleanse and purify them [Prophet], accept a gift out of their property [to make amends] and pray for them- your prayer will be a comfort to them. God is all hearing, all knowing.
Take Sadaqah (alms) from their wealth in order to purify them and sanctify them with it, and invoke Allâh for them. Verily! Your invocations are a source of security for them; and Allâh is All-Hearer, All-Knower.
