Here is how to say the shahada (the Islamic Declaration of Faith), which must be said in Arabic to become a Muslim. I have tried to write it phonetically so that a person who cannot speak Arabic will be able to pronounce each syllable easily. (You will not become a Muslim right now if you just read these words casually, without believing that you are making a formal religious declaration to Almighty God).

(Approximate transliteration of shahada from Arabic):
“Ash-ha-du al-laa i-laa-ha il-lal-lah, wa ash-ha-du an-na Mu-ham-ma-dar Ra-suu-lul-laah.”
And this is the translation: “I bear witness that there is no God except Allah, and I bear witness that Muhammad is the Messenger of Allah.”
It is that simple to become a Muslim. You only have to say those two sentences in Arabic as a Declaration of Faith, and then God will count you as a Muslim.
