﴿ 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”

(He it is Who hath sent among the unlettered ones) the Arabs (a messenger of their own) of their own lineage, i.e. Muhammad (pbuh) (to recite unto them His revelations) the Qur'an which exposits commands and prohibitions (and to make them grow) and to cleanse them from idolatry by means of belief in Allah's divine Oneness; and it is also said this means: He cleanse them by means of them giving the poor-due from their wealth, and also by them repenting; in other words: He invites them to do so, (and to teach them the Scripture) i.e. the Qur'an (and Wisdom) the lawful and the unlawful; it is also said this means: knowledge and the admonitions of the Qur'an, (though heretofore) before the Prophet (pbuh) brought them the Qur'an (they) i.e. the Arabs (were indeed in error manifest) in manifest disbelief,
