Teaching Al Kitaab And Al Hikmah
He purified them by teaching them al-kitab and Hikmah as he purified them by taking Sadqah from them: خُذْ مِنْ أَمْوَالِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكِّيهِم بِهَا وَصَلِّ عَلَيْهِمْ ۖ إِنَّ صَلَاتَكَ سَكَنٌ لَّهُمْ ۗ وَاللَّهُ سَمِيعٌ عَلِيمٌ عطف للبیان can also be translated as “in this way” he purifies them. When people followed his teaching of al-kitab and Hikmah, this very process was meant to purify them.
