وَإِذَا بَدَّلْنَآ ءَايَةًۭ مَّكَانَ ءَايَةٍۢ ۙ وَٱللَّهُ أَعْلَمُ بِمَا يُنَزِّلُ قَالُوٓا۟ إِنَّمَآ أَنتَ مُفْتَرٍۭ ۚ بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَ
How to read it
Wa 'idhā baddalnā 'āyatan mmakāna 'āyatin wa-llahu 'aʻ'lamu bimā yunazzilu qālū 'innamā 'anta muf'tarin . bal' 'ak'tharuhum' lā yaʻ'lamūna
When We substitute one revelation for another,- and Allah knows best what He reveals (in stages),- they say, "Thou art but a forger": but most of them understand not.
Translation: Abdullah Yusuf Ali
