Mishkat al-Masabih 4 Prayer كتاب الصلاة 95

عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الْإِمَامُ ضَامِنٌ وَالْمُؤَذِّنُ مؤتمن الله أَرْشِدِ الْأَئِمَّةَ وَاغْفِرْ لِلْمُؤَذِّنِينَ» . رَوَاهُ أَحْمَدُ وَأَبُو دَاوُدَ وَالتِّرْمِذِيُّ وَالشَّافِعِيُّ وَفِي أُخْرَى لَهُ بِلَفْظِ المصابيح

Abu Huraira reported God’s Messenger as saying, “The imam is responsible and the mu’adhdhin is trusted. O God, guide the imams and forgive the mu’adhdhins .” Ahmad, Abu Dawud, Tirmidhi and Shafi’i transmitted it, and in another version by Shafi’i the wording of al-Masabih is used.
