Narrated Ibn ‘Umar reported God’s Messenger as saying, “Three will be on mounds of musk on the day of resurrection:
a man who gives God and his patron their due, a man who leads people in prayer to their satisfaction, and a man who summons people to the five times of prayer every day and night.”
Tirmidhi transmitted it and said that it is a gharib tradition.
Narrated ‘Uqba b. ‘Amir reported God’s Messenger as saying:
God is pleased with a shepherd on the top of a rock on a mountain who makes the call to prayer and prays. God says, “Look at this servant of Mine who makes the call to prayer, observes the prayer and fears Me. I forgive My servant and will cause him to enter paradise.”
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.”
Ibn ‘Abbas reported God’s Messenger as saying, “If anyone makes the call to prayer for seven years seeking to please God, freedom from hell will be recorded for him.”
