في تَحاكُمِ رَجلَينِ مِن أصحابِهِ إلَى الطاغوتِ و بينَهُما مُنازَعَةٌ في دَينٍ أو مِيراثٍ ـ : مَن تَحاكَمَ إلَى الطاغوتِ فَحُكِمَ لَهُ فإنّما يَأخُذُ سُحتا و إن كانَ حَقُّهُ ثابِتا لَهُ ، لأنّهُ أخَذَ بحُكمِ الطاغوتِ ، و قد أمَرَ اللّهُ أن يَكفُرَ بهِ.
Imam Ja‘far al-Ṣadiq (as):
Imam al-Sadiq (as), with regard to two of his companions who went to be judged before a tyrant in a dispute they had about a loan or inheritance, said, 'Whoever goes to be judged before a tyrant and he judges in favour of one of them, whatever he is compensated is unlawful, even if it was rightfully his, because he took it by judgment of a tyrant when Allah has ordered him to reject the tyrant.'
