Al-Kahf - 18:109

قُل لَّوْ كَانَ الْبَحْرُ مِدَادًا لِّكَلِمَاتِ رَبِّي لَنَفِدَ الْبَحْرُ قَبْلَ أَن تَنفَدَ كَلِمَاتُ رَبِّي وَلَوْ جِئْنَا بِمِثْلِهِ مَدَدًا
[18:109]
Say: If the sea were ink for the words of my Lord, the sea would surely be consumed before the words of my Lord are exhausted, though We were to bring the like of that (sea) to add
Say: "If the ocean were ink (wherewith to write out) the words of my Lord, sooner would the ocean be exhausted than would the words of my Lord, even if we added another ocean like it, for its aid."
Say: Though the sea became ink for the Words of my Lord, verily the sea would be used up before the words of my Lord were exhausted, even though We brought the like thereof to help.
