The Messenger of Allah ﷺ said, "When the muezzin says, 'Allah is the greatest, Allah is the greatest,' and one of you responds, 'Allah is the greatest, Allah is the greatest,' then he says, 'I bear witness that there is no god but Allah,' and the listener says, 'I bear witness that there is no god but Allah,' then he says, 'I bear witness that Muhammad is the Messenger of Allah,' and the listener says, 'I bear witness that Muhammad is the Messenger of Allah,' then he says, 'Come to prayer,' and the listener says, 'There is no power and no strength except through Allah,' then he says, 'Come to success,' and the listener says, 'There is no power and no strength except through Allah,' then he says, 'Allah is the greatest, Allah is the greatest,' and the listener says, 'Allah is the greatest, Allah is the greatest,' then he says, 'There is no god but Allah,' and the listener says, 'There is no god but Allah,' from his heart, he will enter Paradise."
