Al-Kahf 18:109

Qul law kana albahru midadanlikalimati rabbee lanafida albahru qabla an tanfadakalimatu rabbee walaw ji/na bimithlihi madada

Say, "If the sea were ink for [writing] the words of my Lord, the sea would be exhausted before the words of my Lord were exhausted, even if We brought the like of it in [continual] supplement."

Say, “If the ocean were to be ink for (writing) the Words of my Lord, the ocean would have been consumed before the Words of my Lord are exhausted, even though we were to bring another (ocean) like it in addition.”
