highlighted words differ between verses
وَإِن كُنتُمْ فِى رَيْبٍ مِّمَّا نَزَّلْنَا عَلَىٰ عَبْدِنَا فَأْتُوا۟ بِسُورَةٍ مِّن مِّثْلِهِۦ وَٱدْعُوا۟ شُهَدَآءَكُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَـٰدِقِينَ
And if you are in doubt about what We have revealed to Our servant, then produce a sûrah like it and call your helpers other than Allah, if what you say is true.
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ ٱتَّقُوا۟ ٱللَّهَ وَذَرُوا۟ مَا بَقِىَ مِنَ ٱلرِّبَوٰٓا۟ إِن كُنتُم مُّؤْمِنِينَ
O believers! Fear Allah, and give up outstanding interest if you are ˹true˺ believers.
Both end with an 'in kuntum X' conditional — 2:23 challenges doubters with 'in kuntum sadiqin' (if you are truthful) while 2:278 addresses believers with 'in kuntum mu'minin' (if you truly believe), same challenge structure with a swapped qualifier.
