Surah An-Nahl, ayah 95

وَلَا تَشۡتَرُواْ بِعَهۡدِ ٱللَّهِ ثَمَنٗا قَلِيلًاۚ إِنَّمَا عِندَ ٱللَّهِ هُوَ خَيۡرٞ لَّكُمۡ إِن كُنتُمۡ تَعۡلَمُونَ ٩٥

Walā tashtarū bi'ahdillāhi thamanan qalīlan innamā 'indallāhi huwa khayrul lakum in kuntum ta'lamūn

And do not exchange the covenant of Allāh for a small price. Indeed, what is with Allāh is best for you, if only you could know.
