Divine protection of revelation

وَمَآ أَرْسَلْنَا مِن قَبْلِكَ مِن رَّسُولٍ وَلَا نَبِىٍّ إِلَّآ إِذَا تَمَنَّىٰٓ أَلْقَى ٱلشَّيْطَـٰنُ فِىٓ أُمْنِيَّتِهِۦ فَيَنسَخُ ٱللَّهُ مَا يُلْقِى ٱلشَّيْطَـٰنُ ثُمَّ يُحْكِمُ ٱللَّهُ ءَايَـٰتِهِۦ ۗ وَٱللَّهُ عَلِيمٌ حَكِيمٌ

And We did not send before you any messenger or prophet except that when he spoke [or recited], Satan threw into it [some misunderstanding]. But Allāh abolishes that which Satan throws in; then Allāh makes precise His verses. And Allāh is Knowing and Wise.

إِنَّهُمْ عَنِ ٱلسَّمْعِ لَمَعْزُولُونَ

Indeed they, from [its] hearing, are removed.

أَمْ يَقُولُونَ شَاعِرٌ نَّتَرَبَّصُ بِهِۦ رَيْبَ ٱلْمَنُونِ

Or do they say [of you], "A poet for whom we await a misfortune of time"?
