What is the Shar'i ruling on my case, given that my conviction was due to my signing daily papers, and more than two years have passed since the case began, during which I have been detained?

You are a special, trustworthy employee (اجير خاص مؤتمن). You are not liable unless negligence or transgression on your part is proven. Otherwise, you are not liable. Since the matter has reached the Sharia court, the ruling is for it [to decide].
