Linguistically, Islam means submission. According to Islamic terminology, Islam means a specified submission. It is the submission to what the prophet brought. This takes place by uttering the THE TWO TESTIFICATIONS OF FAITH. The Two Testifications of Faith are: I bear witness that no one is God except Allah and I bear witness that Muhammad is the prophet of Allah. Belief, on the other hand, linguistically means certitude. According to Islamic terminology, it means a specified certitude. It is to accept as true what the prophet Muhammad brought. The least of Belief is to belief in the THE TWO TESTIFICATIONS OF FAITH. Islam and Belief cannot be separated. One of them is not accepted without the other, although their original meaning is not identical. Imam Abu Hanifah said in Al-Fiqh Al-'Akbar: "Islam is not acceptable without Belief and Belief is not accepted without Islam. They are like the front of something and its back." Islam is the Religion of all the prophets. Praise be to Allah and may Allah raise the rank of prophet Mohammad.
