Abu Mahdhura said that God's Messenger himself taught him how to make the call to prayer, telling him to say, “God is most great. God is most great. God is most great. God is most great. I testify that there is no god but God. I testify that there is no god but God. I testify that Muhammad is God’s Messenger. I testify that Muhammad is God’s Messenger”; then to repeat, “I testify that there is no god but God. I testify that there is no god but God. I testify that Muhammad is God’s Messenger. I testify that Muhammad is God’s Messenger. Come to prayer. Come to prayer. Come to salvation. Come to salvation. God is most great. God is most great. There is no god but God.” Muslim transmitted it.
