وَٱلَّذِينَ يُؤْمِنُونَ بِمَآ أُنزِلَ إِلَيْكَ وَمَآ أُنزِلَ مِن قَبْلِكَ وَبِٱلْـَٔاخِرَةِ هُمْ يُوقِنُونَ

And who believe in what has been revealed to you, [O Muḥammad], and what was revealed before you, and of the Hereafter they are certain [in faith].

البقرة 4

قُلْ مَن كَانَ عَدُوًّا لِّجِبْرِيلَ فَإِنَّهُۥ نَزَّلَهُۥ عَلَىٰ قَلْبِكَ بِإِذْنِ ٱللَّهِ مُصَدِّقًا لِّمَا بَيْنَ يَدَيْهِ وَهُدًى وَبُشْرَىٰ لِلْمُؤْمِنِينَ

Say, "Whoever is an enemy to Gabriel - it is [none but] he who has brought it [i.e., the Qur’ān] down upon your heart, [O Muḥammad], by permission of Allāh, confirming that which was before it and as guidance and good tidings for the believers."

البقرة 97

وَكَيْفَ تَكْفُرُونَ وَأَنتُمْ تُتْلَىٰ عَلَيْكُمْ ءَايَـٰتُ ٱللَّهِ وَفِيكُمْ رَسُولُهُۥ ۗ وَمَن يَعْتَصِم بِٱللَّهِ فَقَدْ هُدِىَ إِلَىٰ صِرَٰطٍ مُّسْتَقِيمٍ

And how could you disbelieve while to you are being recited the verses of Allāh and among you is His Messenger? And whoever holds firmly to Allāh1 has [indeed] been guided to a straight path.

آل عمران 101

قُلْ يَـٰٓأَهْلَ ٱلْكِتَـٰبِ لَسْتُمْ عَلَىٰ شَىْءٍ حَتَّىٰ تُقِيمُوا۟ ٱلتَّوْرَىٰةَ وَٱلْإِنجِيلَ وَمَآ أُنزِلَ إِلَيْكُم مِّن رَّبِّكُمْ ۗ وَلَيَزِيدَنَّ كَثِيرًا مِّنْهُم مَّآ أُنزِلَ إِلَيْكَ مِن رَّبِّكَ طُغْيَـٰنًا وَكُفْرًا ۖ فَلَا تَأْسَ عَلَى ٱلْقَوْمِ ٱلْكَـٰفِرِينَ

Say, "O People of the Scripture, you are [standing] on nothing until you uphold [the law of] the Torah, the Gospel, and what has been revealed to you from your Lord [i.e., the Qur’ān]." And that which has been revealed to you from your Lord will surely increase many of them in transgression and disbelief. So do not grieve over the disbelieving people.

المائدة 68

وَإِذْ أَوْحَيْتُ إِلَى ٱلْحَوَارِيِّـۧنَ أَنْ ءَامِنُوا۟ بِى وَبِرَسُولِى قَالُوٓا۟ ءَامَنَّا وَٱشْهَدْ بِأَنَّنَا مُسْلِمُونَ

And [remember] when I inspired to the disciples, "Believe in Me and in My messenger [i.e., Jesus]." They said, "We have believed, so bear witness that indeed we are Muslims [in submission to Allāh]."
