What are the rights of the accused in Islamic jurisprudence concerning silence, humane treatment, and knowledge of the charges brought against him?

Scholars have differed regarding the right of the accused to remain silent during interrogation. Some are of the view that he cannot be compelled to answer, while others believe he can be compelled. His silence without a valid excuse may be considered an admission of guilt. The accused has the right to humane treatment and to know the charges against him, and even the reason for which the right was established.
