(Lukman) 31 : 27
وَلَوْ أَنَّمَا فِي الْأَرْضِ مِنْ شَجَرَةٍ أَقْلَامٌ وَالْبَحْرُ يَمُدُّهُ مِنْ بَعْدِهِ سَبْعَةُ أَبْحُرٍ مَا نَفِدَتْ كَلِمَاتُ اللَّهِ ۗ إِنَّ اللَّهَ عَزِيزٌ حَكِيمٌ
If all the trees on earth were used as pens and the sea supplemented with seven more seas used as ink, the Words of Allah wouldn’t be exhausted; indeed Allah is the Exalted, the Wise.
