وَلَوْ اَنَّ مَا فِى الْاَرْضِ مِنْ شَجَرَةٍ اَقْلَامٌ وَّالْبَحْرُ يَمُدُّهٗ مِنْۢ بَعْدِهٖ سَبْعَةُ اَبْحُرٍ مَّا نَفِدَتْ كَلِمٰتُ اللّٰهِ ۗاِنَّ اللّٰهَ عَزِيْزٌ حَكِيْمٌ ( لقمان: ٢٧ )
Wa law annamaa fil ardi min shajaratin aqlaamunw wal bahru yamudduhoo mim ba'dihee sab'atu abhurim maa nafidat Kalimaatul laah; innal laaha 'azeezun Hakeem (Luq̈mān 31:27)
And if whatever trees upon the earth were pens and the sea [was ink], replenished thereafter by seven [more] seas, the words of Allah would not be exhausted. Indeed, Allah is Exalted in Might and Wise. (Luqman  : 27)

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.
