The testimony of faith
is saying with conviction, “La ilaha illa Allah, Muhammadur rasoolu Allah.”
This saying means :
“That none has the right to be worshipped but God alone, and that God has neither partner nor son.
And that Muhammad is the last messenger of God .
This testimony of faith is called the *Shahada*, a simple formula which should be said with conviction in order to convert to Islam .
The testimony of faith is the most important pillar of Islam.
