The Essentials Of Islamic Belief
Islam is the Religion of all the Prophets of Allâh starting with Adam and ending with Muḥammad. In Arabic Islam means submission. To believe in the heart and declare with the tongue: « No one is God except Allâh and Muḥammad is the Messenger of Allâh » is how one becomes Muslim. Utterance with the Two Professions (Ash-Shahadatan) is required of the person who is not already a Muslim. A Muslim is a believer and a follower of Islam.

The Two Testifications Shahadahs
Professing the Two Shahadahs: In regards to the blasphemer who wants to embrace Islam, the belief is not accepted without one uttering the Two Testifications (Shahadahs). In addition, the Muslim is obligated to recite the Two Testifications (Shahadahs) in every prayer for validity of that prayer. The Two Testifications are: I testify that no one is God except Allâh and I testify that Muḥammad is the Messenger of Allâh.
