Example in the Quran

لَقَدۡ مَنَّ ٱللَّهُ عَلَى ٱلۡمُؤۡمِنِينَ إِذۡ بَعَثَ فِيهِمۡ رَسُولٗا مِّنۡ أَنفُسِهِمۡ يَتۡلُواْ عَلَيۡهِمۡ ءَايَٰتِهِۦ وَيُزَكِّيهِمۡ وَيُعَلِّمُهُمُ ٱلۡكِتَٰبَ وَٱلۡحِكۡمَةَ وَإِن كَانُواْ مِن قَبۡلُ لَفِي ضَلَٰلٖ مُّبِينٍ

Indeed, Allah has done the believers a ˹great˺ favour by raising a messenger from among them—reciting to them His revelations, purifying them, and teaching them the Book and wisdom. For indeed they had previously been clearly astray.
