Quran 17:86 from Surah Al-Israa on Divine Marvels.
وَلَئِن شِئۡنَا لَنَذۡهَبَنَّ بِٱلَّذِيٓ أَوۡحَيۡنَآ إِلَيۡكَ ثُمَّ لَا تَجِدُ لَكَ بِهِۦ عَلَيۡنَا وَكِيلًا
English translation: And if We willed We (would) have surely taken away that which We have revealed to you Then not you would find for you concerning it against Us any advocate
Transliteration: wala-in shi'na lanadhhabanna bi-alladhi awhayna ilayka thumma la tajidu laka bihi alayna wakilan
