None has the right to be worshipped except Allah, alone, without partner, to Him belongs all sovereignty and praise and and He is Able to do all things, there is no might nor power except with Allah. None has the right to be worshipped except Allah and we worship none except Him. For Him is all favor, grace, and glorious praise. None has the right to be worshipped except Allah and we are sincere in faith and devotion to Him although the disbelievers detest it.
