Surah Al-Isra — Ayah 86 (17:86)
وَلَئِن شِئۡنَا لَنَذۡهَبَنَّ بِٱلَّذِيٓ أَوۡحَيۡنَآ إِلَيۡكَ ثُمَّ لَا تَجِدُ لَكَ بِهِۦ عَلَيۡنَا وَكِيلًا ٨٦
English translation (Saheeh International)
And if We willed, We could surely do away with that which We revealed to you. Then you would not find for yourself concerning it an advocate against Us.
Brief commentary
By Allah, if I wanted to take away, O Messenger, the revelation I sent to you by erasing it from the hearts and books, I could take it away, then you would not find anyone to help you and take responsibility to return it.
