Quran 18:109 — The Cave (Al-Kahf)

قُل لَو كانَ البَحرُ مِدادًا لِكَلِمٰتِ رَبّى لَنَفِدَ البَحرُ قَبلَ أَن تَنفَدَ كَلِمٰتُ رَبّى وَلَو جِئنا بِمِثلِهِ مَدَدًا

Say, "If the ocean were ink for the words of my Lord, the ocean would run out, before the words of my Lord run out, even if we double the ink supply."

[18:108] Forever they abide therein; they will never want any other substitute.

[18:110] Say, "I am no more than a human like you, being inspired that your god is one god. Those who hope to meet their Lord shall work righteousness, and never worship any other god beside his Lord."
