﴿ هُوَ ٱلَّذِى بَعَثَ فِى ٱلْأُمِّيِّۦنَ رَسُولًۭا مِّنْهُمْ يَتْلُوا۟ عَلَيْهِمْ ءَايَٰتِهِۦ وَيُزَكِّيهِمْ وَيُعَلِّمُهُمُ ٱلْكِتَٰبَ وَٱلْحِكْمَةَ وَإِن كَانُوا۟ مِن قَبْلُ لَفِى ضَلَٰلٍۢ مُّبِينٍۢ ﴾

“He it is who has sent unto the unlettered people an apostle from among themselves, to convey unto them His messages, and to cause them to grow in purity, and to impart unto them the divine writ as well as wisdom - whereas before that they were indeed, most obviously, lost in error”

It is He Who sent to the unlettered folk among the Arabs ummī means ‘one who cannot write or read a book’ a messenger from among them namely Muhammad (s) to recite to them His signs the Qur’ān and to purify them to cleanse them from idolatry and to teach them the Book the Qur’ān and wisdom in the rulings that it contains though indeed wa-in in has been softened from the hardened form with its subject having been omitted that is to say understand it as wa-innahum before that before his coming they had been in manifest error.
