Iman in Islamic theology denotes a believer's faith in the metaphysical aspects of Islam. Its most simple definition is the belief in the six articles of faith, known as arkan al-iman.The term Iman has been delineated in both the Qur'an as well as the Hadith of Gabriel. According to the Qur'an, Iman must be accompanied by righteous deeds and the two together are necessary for entry into Paradise. In the Hadith of Gabriel, Iman in addition to Islam and Ihsan form the three dimensions of the Islamic religion.
