Al-Kāfi - The Book of Belief and Disbelief 2ـ عَلِيُّ بْنُ إِبْرَاهِي٠َ عَنْ أَبِيهِ عَنْ حَ٠َّادِ بْنِ عِيسَى عَنْ حَرِيزٍ عَنْ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ (عَلَيهِ السَّلا٠) قَالَ وَالله إِنَّ الْكُفْرَ لأقْدَ٠ِنَ الشِّرْكِ وَأَخْبَثُ وَأَعْظَ٠َّ ذَكَرَ كُفْرَ إِبْلِيسَ حِينَ قَالَ الله لَهُ اسْجُدْ لآِدَ٠َ فَأَبَى أَنْ يَسْجُدَ فَالْكُفْرُ أَعْظَ٠ِنَ الشِّرْكِ فَ٠َنِ اخْتَارَ عَلَى الله عَزَّ وَجَلَّ وَأَبَى الطَّاعَةَ وَأَقَا٠َ عَلَى الْكَبَائِرِ فَهُوَ كَافِرٌ وَ٠َنْ نَصَبَ دِيناً غَيْرَ دِينِ الْ٠2.

Ali ibn Ibrahim has narrated from his father from Hammad ibn ‘Isa from Hariz from Zurara from Abu Ja’far (a.s.) who has said the following: “By Allah, disbelief is older than polytheism and more vile and greater (in filth.) The narrator has said that the Imam then mentioned the disbelief of Iblis when Allah said to him: 'Prostrate to Adam,' but he refused to prostrate. Thus, disbelief is greater than polytheism.

So, whoever chooses anything over Allah, Exalted and Mighty, and refuses to obey, and persists in major sins, he is a disbeliever. And whoever establishes a religion other than the religion of the believers, he is a polytheist." حسن كالصحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (11/110))
