حَدَّثَنَا ابْنُ مِرْدَاسٍ ، حَدَّثَنَا أَبُو دَاوُدَ ، ثنا أَيُّوبُ بْنُ مَنْصُورٍ ، ثنا شُعَيْبُ بْنُ حَرْبٍ ، نا عَبْدُ الْعَزِيزِ بْنُ أَبِي رَوَّادٍ ، عَنْ نَافِعٍ ، عَنْ مُؤَذِّنٍ لِعُمَرَ ، يُقَالُ لَهُ مَسْرُوحٌ ، أَذَّنَ قَبْلَ الصُّبْحِ فَأَمَرَهُ عُمَرُ ، نَحْوَهُ.
Nafi' reports: The muezzin of Sayyiduna Umar (may Allah be pleased with him), whose name was Masruq, gave the adhan before the true dawn had appeared, so Sayyiduna Umar (may Allah be pleased with him) ordered him. After that, the hadith continues as previously mentioned.
