﴿ وَٱلَّذِىٓ أَوْحَيْنَآ إِلَيْكَ مِنَ ٱلْكِتَٰبِ هُوَ ٱلْحَقُّ مُصَدِّقًۭا لِّمَا بَيْنَ يَدَيْهِ ۗ إِنَّ ٱللَّهَ بِعِبَادِهِۦ لَخَبِيرٌۢ بَصِيرٌۭ ﴾

“And [know that] all of the divine writ with which We have inspired thee is the very truth, confirming the truth of whatever there still remains of earlier revelations for, behold, of [the needs of] His servants God is fully aware, all-seeing.”

And that which We have revealed to you of the Book the Qur’ān is the truth confirming what was revealed before it in other words confirming the Books that came before it. Indeed with regard to His servants God is truly Aware and Seeing knowing both their inward and outward aspects.
