20ـ يُونُسُ عَنِ ابْنِ مُسْكَانَ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ سَمِعْتُهُ يَقُولُ وَمَنْ يُؤْتَ الْحِكْمَةَ فَقَدْ أُوتِيَ خَيْراً كَثِيراً قَالَ مَعْرِفَةُ الإمَامِ وَاجْتِنَابُ الْكَبَائِرِ الَّتِي أَوْجَبَ الله عَلَيْهَا النَّارَ.
20. Yunus has narrated from ibn Muskan from abu Basir who has said the following: “I heard Abu ‘Abdillah (a.s.) saying about, ‘Whoever is given wisdom, certainly, has received much good. . . .,’ (2:269) it (such wisdom) means (having the ability to) recognize the Imam and avoid committing major sins for which Allah has made it necessary to send the perpetrators to fire.’”
