Sura Luqmān 31:27

وَلَوْ أَنَّمَا فِى ٱلْأَرْضِ مِن شَجَرَةٍ أَقْلَٰمٌ وَٱلْبَحْرُ يَمُدُّهُۥ مِنۢ بَعْدِهِۦ سَبْعَةُ أَبْحُرٍ مَّا نَفِدَتْ كَلِمَٰتُ ٱللَّـهِ إِنَّ ٱللَّـهَ عَزِيزٌ حَكِيمٌ

wa-law annamā fī l-arḍi min shajaratin aqlāmun wa-l-baḥru yamudduhu min baʿdihi sabʿatu abḥurin mā nafidat kalimātu allāhi inna allāha ʿazīzun ḥakīmun

And if all the trees on earth were pens and the ocean (were ink), with seven oceans behind it to add to its (supply), yet would not the words of Allah be exhausted (in the writing): for Allah is Exalted in Power, full of Wisdom.
