وَلِيَعْلَمَ ٱلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ أَنَّهُ ٱلْحَقُّ مِن رَّبِّكَ فَيُؤْمِنُوا۟ بِهِۦ فَتُخْبِتَ لَهُۥ قُلُوبُهُمْ ۗ وَإِنَّ ٱللَّهَ لَهَادِ ٱلَّذِينَ ءَامَنُوٓا۟ إِلَىٰ صِرَٰطٍۢ مُّسْتَقِيمٍۢ
And that those who have been given knowledge may know that it is the truth from thy Lord, so that they may believe therein and their hearts may submit humbly unto Him. Lo! Allah verily is guiding those who believe unto a right path.
