وَٱلَّذِيٓ أَوۡحَيۡنَآ إِلَيۡكَ مِنَ ٱلۡكِتَٰبِ هُوَ ٱلۡحَقُّ مُصَدِّقٗا لِّمَا بَيۡنَ يَدَيۡهِۗ إِنَّ ٱللَّهَ بِعِبَادِهِۦ لَخَبِيرُۢ بَصِيرٞ ٣١

And that which We have revealed to you, [O Muḥammad], of the Book is the truth, confirming what was before it. Indeed Allāh, of His servants, is Aware and Seeing.
Brief commentary
The scripture I have revealed to you, O Messenger, is the truth in which there is not doubt, it has been revealed by Allah affirming the precious scriptures. Allah is well informed about His servants and He sees everything. He therefore reveals to the Messenger of every nation what they need in their time.
