The term Shari'ah in Islam refers to a divine law or the path that Allah has ordained for human beings to follow. It is based on the teachings of the Qur'an and the Sunnah (the example set by the Prophet Muhammad) and covers all aspects of a Muslim's life, including personal behavior, morality, and religious duties. Shari'ah is considered to be a source of guidance for Muslims and is a fundamental aspect of Islamic faith and practice. Therefore, the correct option is "a path".
