How will the deaf and mute be judged, and is he obligated to attend Friday prayer?

A person's accountability is solely tied to their intellect. If they are an adult and of sound mind, they are accountable and will be held responsible for their actions, even if they are deaf and cannot hear or speak. They are excused regarding matters of the Shari'ah that did not reach them. However, they will be held accountable for what did reach them and what they understood. The evidence for their accountability is what the jurists mentioned regarding the obligation of Friday prayer upon them, as long as the preacher is not mute. The Hadith also indicates that the deaf, the imbecile, and those who died during an interim period will be tested on the Day of Judgment.
