18:109
قُل لَّوْ كَانَ ٱلْبَحْرُ مِدَادًا لِّكَلِمَـٰتِ رَبِّى لَنَفِدَ ٱلْبَحْرُ قَبْلَ أَن تَنفَدَ كَلِمَـٰتُ رَبِّى وَلَوْ جِئْنَا بِمِثْلِهِۦ مَدَدًا
qul law kāna l-baḥru midādan likalimāti rabbī lanafida l-baḥru qabla an tanfada kalimātu rabbī walaw ji'nā bimith'lihi madadan
Say [Prophet], ‘If the whole ocean were ink for writing the words of my Lord, it would run dry before those words were exhausted’- even if We were to add another ocean to it.
Say (O Muhammad صلى الله عليه وسلم to mankind): "If the sea were ink for (writing) the Words of my Lord, surely, the sea would be exhausted before the Words of my Lord would be finished, even if We brought (another sea) like it for its aid."
