Surah Al-Hajj (The Pilgrimage), Verse 54

وَّلِیَعْلَمَ الَّذِیْنَ اُوْتُوا الْعِلْمَ اَنَّهُ الْحَقُّ مِنْ رَّبِّكَ فَیُؤْمِنُوْا بِهٖ فَتُخْبِتَ لَهٗ قُلُوْبُهُمْ وَاِنَّ اللّٰهَ لَهَادِ الَّذِیْنَ اٰمَنُوْۤا اِلٰی صِرَاطٍ مُّسْتَقِیْمٍ ۟

Wa liya'lamal lazeena ootul 'ilma annahul haqqu mir Rabbika fa yu'minoo bihee fatukhbita lahoo quloobuhum; wa innal laaha lahaadil lazeena aamanoo ilaa Siraatim Mustaqeem

“And that those on whom knowledge has been bestowed may learn that the (Qur'an) is the Truth from thy Lord, and that they may believe therein, and their hearts may be made humbly (open) to it: for verily Allah is the Guide of those who believe, to the Straight Way.”
