﴿ وَإِذَا بَدَّلْنَآ ءَايَةًۭ مَّكَانَ ءَايَةٍۢ ۙ وَٱللَّهُ أَعْلَمُ بِمَا يُنَزِّلُ قَالُوٓا۟ إِنَّمَآ أَنتَ مُفْتَرٍۭ ۚ بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَ ﴾

“And now that We replace one message by another -since God is fully aware of what He bestows from on high, step by step - they [who deny the truth] are wont to say, "Thou but inventest it!" Nay, but most of them do not understand it!”

Sequence of Verses In the previous verse (98), there was an instruction to say اَعُوذ بِاللہ 'a udhu bil-lah' (I seek protection with Allah) while reciting the Qur’ an which indicates that the Shaitan puts scruples in the heart when one recites the Qur'an. In the verses cited above, there is a refutation of such Satanic instigations.
