Sura al-Baqara 2:41

وَءَامِنُوا۟ بِمَآ أَنزَلْتُ مُصَدِّقًا لِّمَا مَعَكُمْ وَلَا تَكُونُوٓا۟ أَوَّلَ كَافِرٍۭ بِهِۦ وَلَا تَشْتَرُوا۟ بِـَٔايَٰتِى ثَمَنًا قَلِيلًا وَإِيَّٰىَ فَٱتَّقُونِ

wa-āminū bimā anzaltu muṣaddiqan li-mā maʿakum wa-lā takūnū awwala kāfirin bihi wa-lā tashtarū bi-āyāti thamanan qalīlan wa-iyyāya fa-attaqūni

And believe in what I reveal, confirming the revelation which is with you, and be not the first to reject Faith therein, nor sell My Signs for a small price; and fear Me, and Me alone.
