Wisdom as supreme wealth and ignorance as poverty
Nahj al-Balāgha|Volume 1|Book 3|Chapter 54
٥٤. وَقَالَ (عليه السلام): لَا غِنَى كَالْعَقْلِ، وَلَا فَقْرَ كَالْجَهْلِ، وَلَا مِيرَاثَ كَالْأَدَبِ، وَلَا ظَهِيرَ كَالْمُشَاوَرَةِ.
54. Amīr al-mu’minīn, peace be upon him, said: There is no wealth like wisdom, no destitution like ignorance, no inheritance like refinement and no support like consultation.
