﴿ لِّيَجْعَلَ مَا يُلْقِى ٱلشَّيْطَٰنُ فِتْنَةًۭ لِّلَّذِينَ فِى قُلُوبِهِم مَّرَضٌۭ وَٱلْقَاسِيَةِ قُلُوبُهُمْ ۗ وَإِنَّ ٱلظَّٰلِمِينَ لَفِى شِقَاقٍۭ بَعِيدٍۢ ﴾

“[And He allows doubts to arise] so that He might cause whatever aspersion Satan may cast [against His prophets] to become a trial for all in whose hearts is disease and all whose hearts are hardened: for, verily, all who are [thus] sinning [against themselves] are most deeply in the wrong.”

(That He may make that which the devil proposeth) on the tongue of his Prophet (a temptation) a misfortune (for those in whose hearts is a disease) doubt and opposition for acting upon it, (and those whose hearts are hardened) towards the remembrance of Allah (Lo! the evil-doers) the idolaters: al-Mughirah Ibn Shu'bah and his host (are in open schism) they are in opposition to, and enmity with, the Truth and guidance.
