Luqman 31:27

Walaw annama fee al-ardi minshajaratin aqlamun walbahru yamudduhu minbaAAdihi sabAAatu abhurin ma nafidat kalimatuAllahi inna Allaha AAazeezun hakeem

And if whatever trees upon the earth were pens and the sea [was ink], replenished thereafter by seven [more] seas, the words of Allāh would not be exhausted. Indeed, Allāh is Exalted in Might and Wise.

And if all trees that are on the earth were to be pens, and the ocean (converted into ink) is supported by seven seas following it, the words of Allah would not come to an end. Surely, Allah is Mighty, Wise.
