[Machine] Saad used to give the call to prayer (adhan) in the mosque of the Messenger of Allah ﷺ . Hafs narrated to me that my family told me that Bilal came to the Messenger of Allah ﷺ to give him the call to prayer for Fajr prayer, but they said that he was sleeping. So Bilal called out in a loud voice, "Prayer is better than sleep", and it was included in the adhan for Fajr prayer. Abu Muhammad said that Saad was called Al-Qaradh.  

أَنَّ سَعْدًا كَانَ يُؤَذِّنُ فِي مَسْجِدِ رَسُولِ اللَّهِ ﷺ قَالَ حَفْصٌ حَدَّثَنِي أَهْلِي أَنَّ بِلَالًا أَتَى رَسُولَ اللَّهِ ﷺ يُؤْذِنُهُ لِصَلَاةِ الْفَجْرِ فَقَالُوا إِنَّهُ نَائِمٌ فَنَادَى بِلَالٌ بِأَعْلَى صَوْتِهِ «الصَّلَاةُ خَيْرٌ مِنَ النَّوْمِ فَأُقِرَّتْ فِي أَذَانِ الْفَجْرِ» قَالَ أَبُو مُحَمَّدٍ يُقَالُ سَعْدٌ الْقَرَظُ
