Certainly did Allah confer [great] favor upon the believers when He sent (3:164)

﴿لَقَدْ مَنَّ اللَّهُ عَلَى الْمُؤْمِنِينَ إِذْ بَعَثَ فِيهِمْ رَسُولًا مِّنْ أَنفُسِهِمْ يَتْلُو عَلَيْهِمْ آيَاتِهِ وَيُزَكِّيهِمْ وَيُعَلِّمُهُمُ الْكِتَابَ وَالْحِكْمَةَ وَإِن كَانُوا مِن قَبْلُ لَفِي ضَلَالٍ مُّبِينٍ﴾
[ آل عمران: 164]

3:164 Certainly did Allah 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 and wisdom, although they had been before in manifest error.

Allah blessed the believers and favoured them when He sent them a messenger from among them, who: recited the Qur’ān to them, purified them from worshipping others next to Allah and from shameful character traits, and taught them the Qur’ān and the ways of the Prophet ( peace be upon him ).
Before this Messenger was sent, they were clearly astray from the right path and guidance.

Indeed Allah conferred a great favour on the believers when He sent among them a Messenger (Muhammad SAW) from among themselves, reciting unto them His Verses (the Quran), and purifying them (from sins by their following him), and instructing them (in) the Book (the Quran) and Al-Hikmah [the wisdom and the Sunnah of the Prophet SAW (i.e. his legal ways, statements, acts of worship, etc.)], while before that they had been in manifest error.
