Today, the rights of persons with disabilities mainly require positive measures by the government in the sense of sovereignty, and due to the various paradigms governing this domain of human rights and citizenship, these entitlements go beyond mere liberty and are raised in the form of claim-rights against legislative, executive and judicial powers. Among these, certain rights – rather than merely meaning protection by the judicial apparatus – signify the necessity of their provision within judicial proceedings, and the human dignity of persons with disabilities, positive discrimination, and the foundation of grace (imtinān) in Islamic law necessitate a distinct right for persons with disabilities in judicial proceedings. Accordingly, the central issue of the present article is the approach and strategies of human rights law and Islamic law in securing the right of persons with disabilities to fair trial.  This descriptive-analytical study concludes that the provision of rights such as the right to an interpreter, the right to equality and impartiality of the judge in proceedings, the right to file class actions, the participation of persons with disabilities in judicial proceedings, their empowerment in litigation, and changing the language of judicial rulings can guarantee justice in judicial processes concerning persons with disabilities; although the Islamic approach with respect to some of these rights enjoys strong guarantees (such as the right to an interpreter), while in regard to others – such as the right of persons with disabilities to participate in judicial proceedings – it exhibits differences that are not entirely aligned with international law.
