Sura al-Māʾidah 5:48

وَأَنزَلْنَآ إِلَيْكَ ٱلْكِتَٰبَ بِٱلْحَقِّ مُصَدِّقًا لِّمَا بَيْنَ يَدَيْهِ مِنَ ٱلْكِتَٰبِ وَمُهَيْمِنًا عَلَيْهِ فَٱحْكُم بَيْنَهُم بِمَآ أَنزَلَ ٱللَّـهُ وَلَا تَتَّبِعْ أَهْوَآءَهُمْ عَمَّا جَآءَكَ مِنَ ٱلْحَقِّ لِكُلٍّ جَعَلْنَا مِنكُمْ شِرْعَةً وَمِنْهَاجًا وَلَوْ شَآءَ ٱللَّـهُ لَجَعَلَكُمْ أُمَّةً وَٰحِدَةً وَلَٰكِن لِّيَبْلُوَكُمْ فِى مَآ ءَاتَىٰكُمْ فَٱسْتَبِقُوا۟ ٱلْخَيْرَٰتِ إِلَى ٱللَّـهِ مَرْجِعُكُمْ جَمِيعًا فَيُنَبِّئُكُم بِمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ

wa-anzalnā ilayka l-kitāba bil-ḥaqqi muṣaddiqan li-mā bayna yadayhi mina l-kitābi wa-muhayminan ʿalayhi fa-aḥkum baynahum bimā anzala allāhu wa-lā tattabiʿ ahwāʾahum ʿammā jāʾaka mina l-ḥaqqi li-kullin jaʿalnā minkum shirʿatan wa-minhājan wa-law shāʾa allāhu lajaʿalakum ummatan wāḥidatan wa-lākin li-yabluwakum fī mā ātakum fa-istabiqū l-khayrāti ilā allāhi marjiʿukum jamīʿan fa-yunabbiʾukum bi-mā kuntum fīhi takhtalifūna

To thee We sent the Scripture in truth, confirming the scripture that came before it, and guarding it in safety: so judge between them by what Allah hath revealed, and follow not their vain desires, diverging from the Truth that hath come to thee. To each among you have we prescribed a law and an open way. If Allah had so willed, He would have made you a single people, but (His plan is) to test you in what He hath given you: so strive as in a race in all virtues. The goal of you all is to Allah; it is He that will show you the truth of the matters in which ye dispute;

Sura al-Aʿrāf 7:163

وَسْـَٔلْهُمْ عَنِ ٱلْقَرْيَةِ ٱلَّتِى كَانَتْ حَاضِرَةَ ٱلْبَحْرِ إِذْ يَعْدُونَ فِى ٱلسَّبْتِ إِذْ تَأْتِيهِمْ حِيتَانُهُمْ يَوْمَ سَبْتِهِمْ شُرَّعًا وَيَوْمَ لَا يَسْبِتُونَ لَا تَأْتِيهِمْ كَذَٰلِكَ نَبْلُوهُم بِمَا كَانُوا۟ يَفْسُقُونَ

wa-sʾalhum ʿani l-qaryati allatī kānat ḥāḍirata l-baḥri idh yaʿdūna fī l-sabti idh taʾtīhim ḥītānuhum yawma sabtihim shurraʿan wa-yawma lā yasbitūna lā taʾtīhim ka-dhālika nablūhum bi-mā kānū yafsuqūna

Ask them concerning the town standing close by the sea. Behold! they transgressed in the matter of the Sabbath. For on the day of their Sabbath their fish did come to them, openly holding up their heads, but on the day they had no Sabbath, they came not: thus did We make a trial of them, for they were given to transgression.

Sura al-Shūrā 42:13

شَرَعَ لَكُم مِّنَ ٱلدِّينِ مَا وَصَّىٰ بِهِۦ نُوحًا وَٱلَّذِىٓ أَوْحَيْنَآ إِلَيْكَ وَمَا وَصَّيْنَا بِهِۦٓ إِبْرَٰهِيمَ وَمُوسَىٰ وَعِيسَىٰٓ أَنْ أَقِيمُوا۟ ٱلدِّينَ وَلَا تَتَفَرَّقُوا۟ فِيهِ كَبُرَ عَلَى ٱلْمُشْرِكِينَ مَا تَدْعُوهُمْ إِلَيْهِ ٱللَّـهُ يَجْتَبِىٓ إِلَيْهِ مَن يَشَآءُ وَيَهْدِىٓ إِلَيْهِ مَن يُنِيبُ

sharaʿa la-kum mina l-dīni mā waṣṣā bihi nūḥan wa-alladhī awḥaynā ilayka wa-mā waṣṣaynā bihi ibrāhīma wa-mūsa wa-ʿīsa an aqīmū l-dīna wa-lā tatafarraqū fīhi kabura ʿalā l-mushrikīna mā tadʿūhum ilayhi allāhu yajtabī ilayhi man yashāʾu wa-yahdī ilayhi man yunību

The same religion has He established for you as that which He enjoined on Noah - the which We have sent by inspiration to thee - and that which We enjoined on Abraham, Moses, and Jesus: Namely, that ye should remain steadfast in religion, and make no divisions therein: to those who worship other things than Allah, hard is the (way) to which thou callest them. Allah chooses to Himself those whom He pleases, and guides to Himself those who turn (to Him).

Sura al-Shūrā 42:21

أَمْ لَهُمْ شُرَكَٰٓؤُا۟ شَرَعُوا۟ لَهُم مِّنَ ٱلدِّينِ مَا لَمْ يَأْذَنۢ بِهِ ٱللَّـهُ وَلَوْلَا كَلِمَةُ ٱلْفَصْلِ لَقُضِىَ بَيْنَهُمْ وَإِنَّ ٱلظَّٰلِمِينَ لَهُمْ عَذَابٌ أَلِيمٌ

am lahum shurakāʾu sharaʿū lahum mina l-dīni mā lam yaʾdhan bihi allāhu wa-lawlā kalimatu l-faṣli la-quḍiya baynahum wa-inna l-ẓālimīna lahum ʿadhābun alīmun

What! have they partners (in godhead), who have established for them some religion without the permission of Allah? Had it not been for the Decree of Judgment, the matter would have been decided between them (at once). But verily the Wrong-doers will have a grievous Penalty.

Sura al-Jāthiyah 45:18

ثُمَّ جَعَلْنَٰكَ عَلَىٰ شَرِيعَةٍ مِّنَ ٱلْأَمْرِ فَٱتَّبِعْهَا وَلَا تَتَّبِعْ أَهْوَآءَ ٱلَّذِينَ لَا يَعْلَمُونَ

thumma jaʿalnāka ʿalā sharīʿatin mina l-amri fa-ittabiʿhā wa-lā tattabiʿ ahwāʾa lladhīna lā yaʿlamūna

Then We put thee on the (right) Way of Religion: so follow thou that (Way), and follow not the desires of those who know not.
