Praise be to Allah.
Any human being can embrace Islam. You do not need anyone’s permission. You simply say and believe that there is No God except Allah and that Mohammad is his Messenger. Once you say this sentence, you automatically become Muslim. From there, you start carrying on with the duties of Islam. You must do what Allah and His messenger tell you to, and stay away from what they tell you to. Islam does not tell you to do anything unless it is good for you. It also does not tell you to stay away from anything unless it is bad for you. You will notice the change in the way you look at things, the minute you become a Muslim. You will feel more relieved and secure only to think that you are fulfilling the orders of Allah. Doing this, you will clearly see the benefits of it for yourself and for mankind. You can embrace Islam in any Islamic center. This is only a formality. Once you say and believe in the Oneness of Allah and in the message of his Prophet Mohammad, then you are a Muslim.
To become a Muslim, simply say the following words:
Ash hadu alla ilaha illa Allah, wa ash hadu anna Mohammadan abduhu wa rasuluhu.
This means I testify and witness that there is no god worthy of being worshipped other than Allah and that Mohammad is his Messenger. You must say it and believe in it.
