Answer:
This is called Shahadah. it is important because it means that you will have to dedicate the rest of your life to Allah
Explanation:
Shahadah translates to "testify" and it's the declaration of faith to only one god (Allah) according to ismalic faith and Mahoma's teachings.
"There is no god but God, Mahoma is the messenger of God" it's the literal translation of the prayer.
Only those who say it honestly, out loud and with the two witnesses required by the traidition, can consider themselves as muslims.
