"The Messenger of Allah said: There are two characteristics in which the Muslims are dependent upon their Mu'adh-dhins: their prayer and their fasting
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُصَفَّى الْحِمْصِيُّ، حَدَّثَنَا بَقِيَّةُ، عَنْ مَرْوَانَ بْنِ سَالِمٍ، عَنْ عَبْدِ الْعَزِيزِ بْنِ أَبِي رَوَّادٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏
"‏ خَصْلَتَانِ مُعَلَّقَتَانِ فِي أَعْنَاقِ الْمُؤَذِّنِينَ لِلْمُسْلِمِينَ صَلاَتُهُمْ وَصِيَامُهُمْ ‏"‏ ‏.‏
