Be Convinced Islam is the True Religion of God to Humanity
بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيم
Praise be to God the Creator of the world, the One Who exists without beginning, without end, without location, without a “how” and Who does not depend on time. Nothing resembles Him in anyway and He hears and sees everything without organs. Whatever you imagine, God is different from that. May the elevation in degree and preservation of his community of what he fears for it, be granted to our master MuHammad Al-‘Amin, the Honest One, who called for following Islam, the religion of truth, the religion of all the Prophets: of the First, Adam, to the last MuHammad.
What is Islam?
Linguistically, Islam means submission, a specified submission. It is the submission to what the prophet brought. This takes place by uttering a statement called 'shahadatayn' - the two testifications of faith. Belief, on the other hand, linguistically means a specified certitude. It is to accept as true what the prophets brought. Islam is not acceptable without Belief and Belief is not accepted without Islam.
The least of Belief is belief in the two testifications of faith, the belief in the oneness of God, Allâh, and in the belief in the Prophets that God sent.
It's important to know that Islam, the submission to one Creator, the belief that there's only ONE God that deserves to be worshiped, is the Religion of all the prophets. There is only one true Religion--that of believing the correct belief in Allâh and His messengers, worshipping Allâh only, loving, respecting, and following the prophet of the time, and loving and respecting other prophets. Every prophet and messenger followed and called people to the same Religion ; this Religion is called ISLAM.
A believer in Islam is called a MUSLIM. And to make it clear, the meaning of Islam is "to submit to Allâh." The meaning of the word Muslim is "one who submits to Allâh." The name Allâh is the name of the only true God. Although prophets and messengers spoke different languages, what they called people to was the same Religion. A person can declare that he believes and follows the true Religion--Islam--in any language, for belief is known to Allâh regardless of the language. Those who say they are Muslim, yet deny the true belief in their heart, with their tongue, or by some actions, are surely not Muslim. Allâh knows fully who are the ones who truly believe in Islam. Both messengers Moses and Jesus called their people to the true Religion--Islam--which is clearly described in the Qur'ân--the last and preserved scripture for all of mankind on earth.
This was a short intro about the meaning of Islam and Muslims.
