Shahadah: the confession of faith.

The confession of faith is the fundamental expression of Islamic faith and the core of all Islamic law; it is very simple:

"There is no God but God and Muhammad is the messenger of God"

(la illaha illa 'lah Muhammadun rasul 'llah).

 The shahadah is the first thing spoken to a newborn and the last thing whispered into the ears of the dead.
