Sura al-Shūrā 42:14

وَمَا تَفَرَّقُوٓا۟ إِلَّا مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْعِلْمُ بَغْيًۢا بَيْنَهُمْ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ إِلَىٰٓ أَجَلٍ مُّسَمًّى لَّقُضِىَ بَيْنَهُمْ وَإِنَّ ٱلَّذِينَ أُورِثُوا۟ ٱلْكِتَٰبَ مِنۢ بَعْدِهِمْ لَفِى شَكٍّ مِّنْهُ مُرِيبٍ

wa-mā tafarraqū illā min baʿdi mā jāʾahumu l-ʿilmu baghyan baynahum wa-lawlā kalimatun sabaqat min rabbika ila ajalin musamman la-quḍiya baynahum wa-inna lladhīna ūrithū l-kitāba min baʿdihim la-fī shakkin minhu murībin

And they became divided only after Knowledge reached them,- through selfish envy as between themselves. Had it not been for a Word that went forth before from thy Lord, (tending) to a Term appointed, the matter would have been settled between them: But truly those who have inherited the Book after them are in suspicious (disquieting) doubt concerning it.

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.
