فَإِذَا قَرَأْتَ ٱلْقُرْءَانَ فَٱسْتَعِذْ بِٱللَّهِ مِنَ ٱلشَّيْطَـٰنِ ٱلرَّجِيمِ ﴿٩٨﴾
So when you recite the Qur’ān, [first] seek refuge in Allāh from Satan, the expelled [from His mercy].
إِنَّهُۥ لَيْسَ لَهُۥ سُلْطَـٰنٌ عَلَى ٱلَّذِينَ ءَامَنُوا۟ وَعَلَىٰ رَبِّهِمْ يَتَوَكَّلُونَ ﴿٩٩﴾
Indeed, there is for him no authority over those who have believed and rely upon their Lord.
إِنَّمَا سُلْطَـٰنُهُۥ عَلَى ٱلَّذِينَ يَتَوَلَّوْنَهُۥ وَٱلَّذِينَ هُم بِهِۦ مُشْرِكُونَ ﴿١٠٠﴾
His authority is only over those who take him as an ally and those who through him associate others with Allāh.
وَإِذَا بَدَّلْنَآ ءَايَةًۭ مَّكَانَ ءَايَةٍۢ ۙ وَٱللَّهُ أَعْلَمُ بِمَا يُنَزِّلُ قَالُوٓا۟ إِنَّمَآ أَنتَ مُفْتَرٍۭ ۚ بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَ ﴿١٠١﴾
And when We substitute a verse in place of a verse - and Allāh is most knowing of what He sends down - they say, "You, [O Muḥammad], are but an inventor [of lies]." But most of them do not know.
قُلْ نَزَّلَهُۥ رُوحُ ٱلْقُدُسِ مِن رَّبِّكَ بِٱلْحَقِّ لِيُثَبِّتَ ٱلَّذِينَ ءَامَنُوا۟ وَهُدًۭى وَبُشْرَىٰ لِلْمُسْلِمِينَ ﴿١٠٢﴾
Say, [O Muḥammad], "The Pure Spirit [i.e., Gabriel] has brought it down from your Lord in truth to make firm those who believe and as guidance and good tidings to the Muslims."
