Belief in divine revelation

وَءَامِنُوا۟ بِمَآ أَنزَلْتُ مُصَدِّقًا لِّمَا مَعَكُمْ وَلَا تَكُونُوٓا۟ أَوَّلَ كَافِرٍۭ بِهِۦ ۖ وَلَا تَشْتَرُوا۟ بِـَٔايَـٰتِى ثَمَنًا قَلِيلًا وَإِيَّـٰىَ فَٱتَّقُونِ

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.

رَبَّنَآ ءَامَنَّا بِمَآ أَنزَلْتَ وَٱتَّبَعْنَا ٱلرَّسُولَ فَٱكْتُبْنَا مَعَ ٱلشَّـٰهِدِينَ

Our Lord, we have believed in what You revealed and have followed the messenger [i.e., Jesus], so register us among the witnesses [to truth]."
