Corruption of religious knowledge

قُلْ يَـٰٓأَهْلَ ٱلْكِتَـٰبِ لَا تَغْلُوا۟ فِى دِينِكُمْ غَيْرَ ٱلْحَقِّ وَلَا تَتَّبِعُوٓا۟ أَهْوَآءَ قَوْمٍ قَدْ ضَلُّوا۟ مِن قَبْلُ وَأَضَلُّوا۟ كَثِيرًا وَضَلُّوا۟ عَن سَوَآءِ ٱلسَّبِيلِ

Say, "O People of the Scripture, do not exceed limits in your religion beyond the truth and do not follow the inclinations of a people who had gone astray before and misled many and have strayed from the soundness of the way."

ٱشْتَرَوْا۟ بِـَٔايَـٰتِ ٱللَّهِ ثَمَنًا قَلِيلًا فَصَدُّوا۟ عَن سَبِيلِهِۦٓ ۚ إِنَّهُمْ سَآءَ مَا كَانُوا۟ يَعْمَلُونَ

They have exchanged the signs of Allāh for a small price and averted [people] from His way. Indeed, it was evil that they were doing.
