In the case of Islam, questions can be raised about what it means . Should everyone who identifies himself or herself as a member of the Islamic community be considered a Muslim, all those who pronounce the double profession of faith (), or only those who perform the prayers, the fast, and the other obligatory rites of Islam? Or is a true Muslim one who tries to conform every aspect of his or her life to the ideals taught in the Qur'an, implemented in the sunna and concretely stipulated in the Islamic law, the shari'a?
