"There is no God but Allah and Muhammed is his messenger"
Shahadah is the first pillar
For Shias, Shahadah is a belief rather than a practice, so it is not an obligatory act.
It is a simple yet profound statement expressing a Muslim's complete acceptance of and commitment to Islam.
Reminds Muslims of the oneness of God - Tawhid - viewed a fundamentally important Islamic belief.
Reminds Muslims of the importance of Prophet Muhammed and the Qurans (+ its teachings).
The Shahadah is...
The first thing new-born babies hear
Recited during the call to prayer and Salah
Repeated when someone wishes to convert to Islam with a witness present
Said before death to demonstrate commitment to Islam
Reminder for Muslims to bear witness to the truth of Islam by sharing it with others
Is Shahadah the most important pillar?
Agree: It is the declaration of faith and is needed to become a Muslim. It sums up the Islamic faith and is the first of the five pillars and the first words you hear as a Muslim.
Disagree: All the pillars are equally important. They are all duties that must be performed, one cannot be singled out from the others. Salah could be more important as it happens 5 times a day and is about connecting to God. Zakah could be more important as it helps others in a practical way.
