The testimony
To become Muslim, a person sincerely believes and declares that none has the right to be worshipped except Allah, and that Muhammad is His final Messenger. No ceremony or witness is strictly required — it is between you and Allah, though telling your local mosque helps you find support.
أَشْهَدُ أَنْ لَا إِلَٰهَ إِلَّا اللَّهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ
Ash-hadu an la ilaha illallah, wa ash-hadu anna Muhammadan rasulullah.
