I heard the Messenger of Allah ﷺ say, "The caller to prayer is forgiven to the extent of his voice's reach, and every moist and dry thing seeks forgiveness for him. The one who attends the prayer has twenty-five good deeds recorded for him, and what is between the two prayers is expiated for him."
حدثنا أبو بكر بن أبي شيبة حدثنا شبابة حدثنا شعبة عن موسى بن أبي عثمان عن أبي يحيى
سمعت رسول الله ﷺ يقول المؤذن يغفر له مدى صوته ويستغفر له كل رطب ويابس وشاهد الصلاة يكتب له خمس وعشرون حسنة ويكفر عنه ما بينهما
