٤٧٨. وَقَالَ (عليه ‏السلام): مَا أَخَذَ اللهُ عَلَى أَهْلِ الْجَهْلِ أَنْ يَتَعَلَّمُوا حَتَّى أَخَذَ عَلَى أَهْلِ الْعِلْمِ أَنْ يُعَلِّمُوا.
478. Amīr al-mu’minīn, peace be upon him, said: Allāh has not made it obligatory on the ignorant to learn till He has made it obligatory on the learned to teach.
