Al Baqarah, 41 Ayah
2:41
وَءَامِنُواْ بِمَآ أَنزَلۡتُ مُصَدِّقٗا لِّمَا مَعَكُمۡ وَلَا تَكُونُوٓاْ أَوَّلَ كَافِرِۭ بِهِۦۖ وَلَا تَشۡتَرُواْ بِـَٔايَٰتِي ثَمَنٗا قَلِيلٗا وَإِيَّٰيَ فَٱتَّقُونِ ٤١
Wa 'Āminū Bimā 'Anzaltu Muşaddiqāan Limā Ma`akum Wa Lā Takūnū 'Awwala Kāfirin Bihi ۖ Wa Lā Tashtarū Bi'āyātī Thamanāan Qalīlāan Wa 'Īyāya Fa Attaqūni
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.
