I bear witness that none has the right to be worshipped but Allah alone, Who has no partner, and that Muhammad is His slave and His Messenger. I am pleased with Allah as my Lord, with Muhammad as my Messenger and with Islam as my religion.1 [To be recited in Arabic after the mu'adh-dhin's tashahhud or the words of affirmation of Faith] 2
