خُذْ مِنْ أَمْوَٰلِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكِّيهِم بِهَا وَصَلِّ عَلَيْهِمْ ۖ إِنَّ صَلَوٰتَكَ سَكَنٌ لَّهُمْ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ
Commentary:
The persons referred to in the preceding verse brought a part of their property and begged the Holy Prophet to take the same as alms, but he told them that he had no instructions to accept anything from them, whereupon this verse was revealed, allowing him to accept their alms and to pray for them.
