Chapter 8 | The obligation to obey the Imams
12ـ عَلِيٌّ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ عَنْ مُحَمَّدِ بْنِ الْفُضَيْلِ قَالَ سَأَلْتُهُ عَنْ أَفْضَلِ مَا يَتَقَرَّبُ بِهِ الْعِبَادُ إِلَى الله عَزَّ وَجَلَّ قَالَ أَفْضَلُ مَا يَتَقَرَّبُ بِهِ الْعِبَادُ إِلَى الله عَزَّ وَجَلَّ طَاعَةُ الله وَطَاعَةُ رَسُولِهِ وَطَاعَةُ أُولِي الامْرِ قَالَ أَبُو جَعْفَرٍ حُبُّنَا إِيمَانٌ وَبُغْضُنَا كُفْرٌ.
12. Ali has narrated from Muhammad ibn ‘Isa from Yunus from Muhammad ibn Fudayl who has said that I asked the Imam about such a matter that would take people closer to Allah. The Imam said, “Of the matters that can take people closer to Allah, the Most Holy, the Most High, the best one is to obey Him, His messenger and those who posses Divine authority.” Imam abu Ja‘far has said, “To love us if faith and to harbor hatred towards us is disbelief.”
