Aal-'Imran - 3:164

لَقَدْ مَنَّ اللّهُ عَلَى الْمُؤمِنِينَ إِذْ بَعَثَ فِيهِمْ رَسُولاً مِّنْ أَنفُسِهِمْ يَتْلُو عَلَيْهِمْ آيَاتِهِ وَيُزَكِّيهِمْ وَيُعَلِّمُهُمُ الْكِتَابَ وَالْحِكْمَةَ وَإِن كَانُواْ مِن قَبْلُ لَفِي ضَلالٍ مُّبِينٍ
[3:164]
Certainly Allah conferred a benefit upon the believers when He raised among them a Messenger from among themselves, reciting to them His communications and purifying them, and teaching them the Book and the wisdom, although before that they were surely in manifest error.
Allah did confer a great favour on the believers when He sent among them a messenger from among themselves, rehearsing unto them the Signs of Allah, sanctifying them, and instructing them in Scripture and Wisdom, while, before that, they had been in manifest error.
Allah verily hath shown grace to the believers by sending unto them a messenger of their own who reciteth unto them His revelations, and causeth them to grow, and teacheth them the Scripture and wisdom; although before (he came to them) they were in flagrant error.
