To embrace Islam, you need to say the Shahadah (testimony of faith) in Arabic as well as your tongue language. It is something to be said with the tongue anytime, anywhere, but must be said with sincere conviction in the heart.

Full Shahadah sentence:

In Arabic:
"أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهَ، وَ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللهِ."

In English:
"I bear witness that there is no deity worthy of worship except Allah, and I bear witness that Muhammad is the Messenger of Allah."
