 ١٨ـ عَلِيٌّ عَنْ أَبِيهِ عَنْ أَبِي هَاشِمٍ الْجَعْفَرِيِّ قَالَ كُنَّا عِنْدَ الرِّضَا (عَلَيْهِ السَّلام) فَتَذَاكَرْنَا الْعَقْلَ وَالادَبَ فَقَالَ يَا أَبَا هَاشِمٍ الْعَقْلُ حِبَاءٌ مِنَ الله وَالادَبُ كُلْفَةٌ فَمَنْ تَكَلَّفَ الادَبَ قَدَرَ عَلَيْهِ وَمَنْ تَكَلَّفَ الْعَقْلَ لَمْ يَزْدَدْ بِذَلِكَ إِلا جَهْلاً.
 18. Ali has narrated from his father from abu Hashim al-Ja‘fari who has said the following. “We were in the presence of Imam al-Rida (a.s) that a discussion about intelligence took place and the Imam said, “O abu Hashim, intelligence is a present from Allah but discipline is a skill and burden. One who would pretend as a well disciplined one he would certainly establish full control in it. But to pretend as a person of intelligence would increase in him nothing but more ignorance.”
