And if whatever trees upon the earth were pens and the sea [was ink], replenished thereafter by seven [more] seas, the words1 of Allāh would not be exhausted. Indeed, Allāh is Exalted in Might and Wise.
If all the trees on Earth were to be cut and made into pens, and the seas multiplied by seven and turned into ink, the Words of Allah would not finish due to their being infinite. Indeed, Allah is the Almighty whom none can overcome; the Wise in His creation and decree.
