মিশকাতুল মাসাবীহ ৬১৩

If anyone says when he hears the summons, “O God, Lord of this perfect call and of the prayer which is established for all time, grant Muhammad the wasila and excellency, and raise him up in a praiseworthy position (Al-Qur’an; 17:79) which Thou hast promised,” he will be assured of my intercession.

Bukhari transmitted it.

If anyone says when he hears the mu’adhdhin, “I testify that there is no god but God alone who has no partner and that Muhammad is His servant and Messenger; I am satisfied with God as Lord, with Muhammad as Messenger, and with Islam as religion,” his sins will be forgiven him.

Muslim transmitted it.

When the mu’adhdhin says, “God is most great, God is most great,” and one of you makes the response, “God is most great, God is most great”; then says, “I testify that there is no god but God,” and he makes the response, “I testify that there is no god but God”; then says, “I testify that Muhammad is God’s Messenger,” and he makes the response, “I testify that Muhammad is God’s Messenger”; then says, “Come to prayer,” and he makes the response, “There is no might and no power except in God”; then says, “Come to salvation,” and he makes the response, “There is no might and no power except in God”; then says, “God is most great, God is most great,” and he makes the response, “God is most great, God is most great”; then says, “There is no god but God,” and he makes the response, “There is no god but God”; if he says this from his heart, he will enter paradise.
