‘Umar b. al-khattab reported the Messenger of Allah (May peace be upon him) as saying; When the MU’ADHDHIN says

When the mu'adhin says: "Allah is the Greatest, Allah is the Greatest," and one of you says: "Allah is the Greatest, Allah is the Greatest"; then when he says: "I bear witness that there is no god but Allah," he says: "I bear witness that there is no god but Allah"; then when he says: "I bear witness that Muhammad is the Messenger of Allah," he says: "I bear witness that Muhammad is the Messenger of Allah"; then he says: "Come to prayer," he says: "There is no might and no power except with Allah"; then he says: "Come to success," he says: "There is no might and no power except with Allah"; then he says: "Allah is the Greatest, Allah is the Greatest," he says: "Allah is the Greatest, Allah is the Greatest"; then he says: "There is no god but Allah," he says: "There is no god but Allah" from his heart, he will enter Paradise.
