Yes of course you can
and it is very easy, if you believe that there is only ONE God and Muhammad is a messenger of God, then all you have to do is say with Sincerity the following:
I bear witness that there is no God except Allah, and
I bear witness that Muhammad is a messenger of Allah.
Then you say it in the Arabic language: listen to the Audio below and repeat after it:
(Ash-hadu an La ilaha illa ALLAH, Wa Ash-hadu an Muhammadan Rasool ALLAH)
