Surah 2 : Ayah 41

وَءَامِنُوا۟ بِمَآ أَنزَلْتُ مُصَدِّقًا لِّمَا مَعَكُمْ وَلَا تَكُونُوٓا۟ أَوَّلَ كَافِرٍۭ بِهِۦ ۖ وَلَا تَشْتَرُوا۟ بِـَٔايَـٰتِى ثَمَنًا قَلِيلًا وَإِيَّـٰىَ فَٱتَّقُونِ

And believe in what I have sent down[25] which confirms that [Scripture] which is with you, and do not be the first to disbelieve in it, nor trade my verses for a small price, and fear Me alone.
