Reading this one sentence in Arabic (which is called ‘Shahada’) will make you a Muslim now:
1. The Shahada in Arabic
أَشْهَدُ
أَنْ لَا
إِلَٰهَ
إِلَّا اللّٰه
وَأَشْهَدُ
أَنَّ
مُحَمَّدًا
رَسُولُ اللَّهِ
2. Pronouncing the Shahada
Say these words clearly:
Ash-Hadu An La Ilaha Illa-Allah Wa Ash-Hadu Anna Mohammadan Rasool-ul-Allah
This is how we declare our faith in Islam.
3. Understanding the Shahada
These words mean:
“I bear witness that there is no god but Allah (the Only God), and I bear witness that Muhammad (peace be upon him) is the Messenger of Allah.”
Believe this in your heart, and say it sincerely to become Muslim.
