How to become a Muslim
The word "Muslim" means one who submits to God, regardless of race, nationality, or ethnic background. Becoming a Muslim is a simple and easy process that requires no complex rituals or ceremony. You may convert alone in privacy or you may do so in the presence of others. The actual act of accepting Islam is between you and your Creator.
If anyone has a genuine desire to be a Muslim and has full conviction and strong belief that Islam is the true religion of God, then, all one needs to do is pronounce the "Shahada", the testimony of faith, without delay.
With the pronunciation of this testimony, or "Shahada", with sincere belief and conviction, one enters the fold of Islam.
Upon entering the fold of Islam solely for the pleasure of God, all your previous sins are forgiven, and you start a new life.
Your record is clean and it is as if he was just born from your mother's womb. You should try as much as possible to maintain the clean record and strive to do as many good deeds as possible.
“Once you say these words with conviction and understanding, you become a Muslim in the sight of God.
