Quran 17:86 Al-Isra, ayah 86 of 111

وَلَئِن شِئْنَا لَنَذْهَبَنَّ بِٱلَّذِىٓ أَوْحَيْنَآ إِلَيْكَ ثُمَّ لَا تَجِدُ لَكَ بِهِۦ عَلَيْنَا وَكِيلًا ۝٨٦

17:86 And if We willed We could withdraw that which We have revealed unto thee, then wouldst thou find no guardian for thee against Us in respect thereof.
