The Prophet's mission (tilawah, tazkiyyah, ta'lim)

لَقَدْ مَنَّ ٱللَّهُ عَلَى ٱلْمُؤْمِنِينَ إِذْ بَعَثَ فِيهِمْ رَسُولًا مِّنْ أَنفُسِهِمْ يَتْلُوا۟ عَلَيْهِمْ ءَايَـٰتِهِۦ وَيُزَكِّيهِمْ وَيُعَلِّمُهُمُ ٱلْكِتَـٰبَ وَٱلْحِكْمَةَ وَإِن كَانُوا۟ مِن قَبْلُ لَفِى ضَلَـٰلٍ مُّبِينٍ

Certainly did Allāh confer [great] favor upon the believers when He sent among them a Messenger from themselves, reciting to them His verses and purifying them and teaching them the Book [i.e., the Qur’ān] and wisdom, although they had been before in manifest error.
