Mishkat al-Masabih 667

Abu Huraira reported God’s Messenger as saying, “The mu'adhdhin will receive forgiveness to the extent to which his voice reaches, and every moist and dry place will testify on his behalf; and he who attends prayer will have twenty-five prayers recorded for him and will have expiation for sins committed between every two times of prayer.” Ahmad, Abu Dawud and Ibn Majah transmitted it, and Nasa’i transmitted up to “every moist and dry place will testify on his behalf,” adding “and he will have a reward equal to that of those who pray.”
