وَلَوْ اَنَّمَا فِی الْاَرْضِ مِنْ شَجَرَةٍ اَقْلَامٌ وَّالْبَحْرُ یَمُدُّهٗ مِنْ بَعْدِهٖ سَبْعَةُ اَبْحُرٍ مَّا نَفِدَتْ كَلِمٰتُ اللّٰهِ اِنَّ اللّٰهَ عَزِیْزٌ حَكِیْمٌ ۟

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

“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.”
