كَانَ ٱلنَّاسُ أُمَّةً وَٰحِدَةً فَبَعَثَ ٱللَّهُ ٱلنَّبِيِّـۧنَ مُبَشِّرِينَ وَمُنذِرِينَ وَأَنزَلَ مَعَهُمُ ٱلْكِتَـٰبَ بِٱلْحَقِّ لِيَحْكُمَ بَيْنَ ٱلنَّاسِ فِيمَا ٱخْتَلَفُوا۟ فِيهِ ۚ وَمَا ٱخْتَلَفَ فِيهِ إِلَّا ٱلَّذِينَ أُوتُوهُ مِنۢ بَعْدِ مَا جَآءَتْهُمُ ٱلْبَيِّنَـٰتُ بَغْيًۢا بَيْنَهُمْ ۖ فَهَدَى ٱللَّهُ ٱلَّذِينَ ءَامَنُوا۟ لِمَا ٱخْتَلَفُوا۟ فِيهِ مِنَ ٱلْحَقِّ بِإِذْنِهِۦ ۗ وَٱللَّهُ يَهْدِى مَن يَشَآءُ إِلَىٰ صِرَٰطٍ مُّسْتَقِيمٍ

Mankind was [of] one religion [before their deviation]; then Allāh sent the prophets as bringers of good tidings and warners and sent down with them the Scripture in truth to judge between the people concerning that in which they differed. And none differed over it [i.e., the Scripture] except those who were given it - after the clear proofs came to them - out of jealous animosity among themselves. And Allāh guided those who believed to the truth concerning that over which they had differed, by His permission. And Allāh guides whom He wills to a straight path.

Al-Baqarah 213

قُولُوٓا۟ ءَامَنَّا بِٱللَّهِ وَمَآ أُنزِلَ إِلَيْنَا وَمَآ أُنزِلَ إِلَىٰٓ إِبْرَٰهِـۧمَ وَإِسْمَـٰعِيلَ وَإِسْحَـٰقَ وَيَعْقُوبَ وَٱلْأَسْبَاطِ وَمَآ أُوتِىَ مُوسَىٰ وَعِيسَىٰ وَمَآ أُوتِىَ ٱلنَّبِيُّونَ مِن رَّبِّهِمْ لَا نُفَرِّقُ بَيْنَ أَحَدٍ مِّنْهُمْ وَنَحْنُ لَهُۥ مُسْلِمُونَ

Say, [O believers], "We have believed in Allāh and what has been revealed to us and what has been revealed to Abraham and Ishmael and Isaac and Jacob and the Descendants [al-Asbāṭ]1 and what was given to Moses and Jesus and what was given to the prophets from their Lord. We make no distinction between any of them, and we are Muslims [in submission] to Him."

Al-Baqarah 136

وَكَذَٰلِكَ جَعَلْنَـٰكُمْ أُمَّةً وَسَطًا لِّتَكُونُوا۟ شُهَدَآءَ عَلَى ٱلنَّاسِ وَيَكُونَ ٱلرَّسُولُ عَلَيْكُمْ شَهِيدًا ۗ وَمَا جَعَلْنَا ٱلْقِبْلَةَ ٱلَّتِى كُنتَ عَلَيْهَآ إِلَّا لِنَعْلَمَ مَن يَتَّبِعُ ٱلرَّسُولَ مِمَّن يَنقَلِبُ عَلَىٰ عَقِبَيْهِ ۚ وَإِن كَانَتْ لَكَبِيرَةً إِلَّا عَلَى ٱلَّذِينَ هَدَى ٱللَّهُ ۗ وَمَا كَانَ ٱللَّهُ لِيُضِيعَ إِيمَـٰنَكُمْ ۚ إِنَّ ٱللَّهَ بِٱلنَّاسِ لَرَءُوفٌ رَّحِيمٌ

And thus We have made you a median [i.e., just] community that you will be witnesses over the people and the Messenger will be a witness over you. And We did not make the qiblah which you used to face except that We might make evident who would follow the Messenger from who would turn back on his heels.1 And indeed, it is difficult except for those whom Allāh has guided. And never would Allāh have caused you to lose your faith [i.e., your previous prayers]. Indeed Allāh is, to the people, Kind and Merciful.

Al-Baqarah 143

قُلْ ءَامَنَّا بِٱللَّهِ وَمَآ أُنزِلَ عَلَيْنَا وَمَآ أُنزِلَ عَلَىٰٓ إِبْرَٰهِيمَ وَإِسْمَـٰعِيلَ وَإِسْحَـٰقَ وَيَعْقُوبَ وَٱلْأَسْبَاطِ وَمَآ أُوتِىَ مُوسَىٰ وَعِيسَىٰ وَٱلنَّبِيُّونَ مِن رَّبِّهِمْ لَا نُفَرِّقُ بَيْنَ أَحَدٍ مِّنْهُمْ وَنَحْنُ لَهُۥ مُسْلِمُونَ

Say, "We have believed in Allāh and in what was revealed to us and what was revealed to Abraham, Ishmael, Isaac, Jacob, and the Descendants [al-Asbāṭ], and in what was given to Moses and Jesus and to the prophets from their Lord. We make no distinction between any of them, and we are Muslims [submitting] to Him."

Ali 'Imran 84

أُو۟لَـٰٓئِكَ ٱلَّذِينَ هَدَى ٱللَّهُ ۖ فَبِهُدَىٰهُمُ ٱقْتَدِهْ ۗ قُل لَّآ أَسْـَٔلُكُمْ عَلَيْهِ أَجْرًا ۖ إِنْ هُوَ إِلَّا ذِكْرَىٰ لِلْعَـٰلَمِينَ

Those are the ones whom Allāh has guided, so from their guidance take an example. Say, "I ask of you for it [i.e., this message] no payment. It is not but a reminder for the worlds."
