16:101
وَإِذَا بَدَّلْنَآ ءَايَةً مَّكَانَ ءَايَةٍ ۙ وَٱللَّهُ أَعْلَمُ بِمَا يُنَزِّلُ قَالُوٓا۟ إِنَّمَآ أَنتَ مُفْتَرٍۭ ۚ بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَ
wa-idhā baddalnā āyatan makāna āyatin wal-lahu aʿlamu bimā yunazzilu qālū innamā anta muf'tarin bal aktharuhum lā yaʿlamūna
When We substitute one revelation for another- and God knows best what He reveals- they say, ‘You are just making it up,’ but most of them have no knowledge.
And when We change a Verse (of the Qur’ân,) in place of another - and Allâh knows best what He sends down - they (the disbelievers) say: "You (O Muhammad صلى الله عليه و سلم) are but a Muftari! (forger, liar)." Nay, but most of them know not.
