This is the reason why co working with them, helping, & assisting them except where there exists a necessity like eating (haram & prohibited) blood & corpse (deal body) for saving of life etc.) is prohibited.
(تحف العقول ص332) Indeed the cognition & knowing of Allah provides comfort in all terrors & frights. And it is the companion in all solitudes & loneliness’s & the light in all darkness’s & energy in all weaknesses & feebleness’s & the cure of all diseases & ailments. [^2] 2- ... اِنَّ مَعرِفَةَ اللهِ عَزَّوَجَلَّ آنِسٌ مِن کُلِّ وَحشَةٍ، وَصاحِبٌ مِن کُلِّ وَحدَةٍ، وَنُورٌ مِن کُلِّ ظُلمَةٍ، وَقُوَّةٌ مِن کُلِّ ضَعفٍ،وَشِفاءٌ مِن کُلِّ سُقيمٍ.
(فروغ الکافی ج8 ص247) Umer bin Hazala says I enquired from Imam Ja’far Sadiq (as) "Two men out of us have a dispute about a debt or a heritage & proceed toward the king & the judges of the age (appointed by the king) to get their affair settled. Is this act of theirs lawful?' Imam Sadiq said, 'Anyone who refers to them for Judgment of whether something right or false, so truly he has referred to Taghut (Satan, Devil).
And what so ever judgment the (satanic institution,) executes for him (should that even be a right one) is getting (haram) Prohibited wealth, because, he gets it upon the order of false deity, (Satan). Whereas, Allah has commanded in the Holy Quran to deny the Satan & devil.
