﴿ وَهَٰذَا كِتَٰبٌ أَنزَلْنَٰهُ مُبَارَكٌۭ مُّصَدِّقُ ٱلَّذِى بَيْنَ يَدَيْهِ وَلِتُنذِرَ أُمَّ ٱلْقُرَىٰ وَمَنْ حَوْلَهَا ۚ وَٱلَّذِينَ يُؤْمِنُونَ بِٱلْءَاخِرَةِ يُؤْمِنُونَ بِهِۦ ۖ وَهُمْ عَلَىٰ صَلَاتِهِمْ يُحَافِظُونَ ﴾

“And this, too, is a divine writ which We have bestowed from on high - blessed, confirming the truth of whatever there still remains [of earlier revelations] -and [this] in order that thou mayest warn the foremost of all cities and all who dwell around it. And those who believe in the life to come do believe in this [warning]; and it is they who are ever-mindful of their prayers.”

And this Qur’ān is a blessed Book We have revealed confirming that which was before it of scriptures and that you may warn li-tundhira or read li-yundhira ‘that it may warn’ as supplement to the import of the preceding statement sc. ‘to confirm that which was before it and to warn’ in other words We have revealed it for the blessings it gives as a vindication of previous scripture and for you to warn therewith the Mother of Towns and those around it that is the inhabitants of Mecca and all other people; and those who believe in the Hereafter believe in it and they observe their prayers fearing the punishment thereof.
