وَءَامِنُوا بِمَآ أَنزَلْتُ مُصَدِّقًا لِّمَا مَعَكُمْ وَلَا تَكُونُوٓا أَوَّلَ كَافِرٍۭ بِهِۦ ۖ وَلَا تَشْتَرُوا بِـَٔايَـٰتِى ثَمَنًا قَلِيلًا وَإِيَّـٰىَ فَٱتَّقُونِ

Waaminoo bima anzaltu musaddiqanlima maAAakum wala takoonoo awwala kafirinbihi wala tashtaroo bi-ayatee thamananqaleelan wa-iyyaya fattaqoon

And believe in what I have sent down confirming that which is [already] with you, and be not the first to disbelieve in it. And do not exchange My signs for a small price, and fear [only] Me.
