أَخْبَرَنَا عُثْمَانُ بْنُ عُمَرَ بْنِ فَارِسٍ ، حَدَّثَنَا يُونُسُ ، عَنْ الزُّهْرِيِّ ، عَنْ حَفْصِ بْنِ عُمَرَ بْنِ سَعْدٍ الْمُؤَذِّنِ، أَنَّ " سَعْدًا كَانَ يُؤَذِّنُ فِي مَسْجِدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ "، قَالَ حَفْصٌ : حَدَّثَنِي أَهْلِي ، أَنَّ بِلَالًا أَتَى رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُؤْذِنُهُ لِصَلَاةِ الْفَجْرِ، فَقَالُوا : إِنَّهُ نَائِمٌ،" فَنَادَى بِلَالٌ بِأَعْلَى صَوْتِهِ : الصَّلَاةُ خَيْرٌ مِنْ النَّوْمِ، فَأُقِرَّتْ فِي أَذَانِ صَلَاةِ الْفَجْرِ ".
قَالَ أَبُو مُحَمَّد : يُقَالُ : سَعْدٌ الْقَرَظُ

Othman bin Omar bin Faris told us, Yunus told us, on the authority of Al-Zuhri, on the authority of Hafs bin Omar bin Saad, the muezzin, that “Saad was giving the call to prayer In the mosque of the Messenger of God, may God bless him and grant him peace. Hafs said: My family told me that Bilal came to the Messenger of God, may God bless him and grant him peace, to give him the call to prayer. For the Fajr prayer, and they said: He is asleep. Then Bilal called out at the top of his voice: Prayer is better than sleep, so it was confirmed in the call to prayer for the Fajr prayer.
Abu Muhammad said: It is said: Saad Al-Qardh
