إِنَّ مِنْ آخِرِ مَا عَهِدَ إِلَىَّ رَسُولُ اللَّهِ ﷺ أَنِ اتَّخِذْ مُؤَذِّنًا لاَ يَأْخُذُ عَلَى أَذَانِهِ أَجْرًا  

قَالَ أَبُو عِيسَى حَدِيثُ عُثْمَانَ حَدِيثٌ حَسَنٌ وَالْعَمَلُ عَلَى هَذَا عِنْدَ أَهْلِ الْعِلْمِ كَرِهُوا أَنْ يَأْخُذَ الْمُؤَذِّنُ عَلَى الأَذَانِ أَجْرًا وَاسْتَحَبُّوا لِلْمُؤَذِّنِ أَنْ يَحْتَسِبَ فِي أَذَانِهِ
