17:86
وَلَئِن شِئْنَا لَنَذْهَبَنَّ بِٱلَّذِىٓ أَوْحَيْنَآ إِلَيْكَ ثُمَّ لَا تَجِدُ لَكَ بِهِۦ عَلَيْنَا وَكِيلًا
wala-in shi'nā lanadhhabanna bi-alladhī awḥaynā ilayka thumma lā tajidu laka bihi ʿalaynā wakīlan
If We pleased, We could take away what We have revealed to you- then you would find no one to plead for you against Us-
And if We willed, We could surely take away that which We have revealed to you (i.e. this Qur’ân). Then you would find no protector for you against Us in that respect.
