وَآمِنُوا بِمَا أَنزَلْتُ مُصَدِّقًا لِّمَا مَعَكُمْ وَلَا تَكُونُوا أَوَّلَ كَافِرٍ بِهِ ۖ وَلَا تَشْتَرُوا بِآيَاتِي ثَمَنًا قَلِيلًا وَإِيَّايَ فَاتَّقُونِ (41)
(2:41) And believe in the Book I have now sent down; as it confirms the Scriptures you already possess, be not the first to reject it; barter not away My Revelations for paltry worldly gain, *57 and guard yourselves against My wrath
*57). 'Trifling gain' refers to the worldly benefits for the sake of which they were rejecting God's directives. Whatever one may gain in exchange for the Truth, be it all the treasure in the world, is trifling; the Truth is of supreme value.
