bayhaqi:5744Abū ʿAbdullāh al-Ḥāfiẓ > Abū al-ʿAbbās al-Qāsim b. al-Qāsim b. ʿAbdullāh al-Sayyārī Bimarw > Abū al-Muwajjih > ʿAbdān > ʿAbdullāh > Yūnus b. Yazīd > al-Zuhrī > al-Sāʾib b. Yazīd > al-Adhān al-Awwal

[Machine] On the first day of Friday, it was the first time that the Imam sat on the pulpit during the time of the Messenger of Allah ﷺ , as well as during the time of Abu Bakr and Umar. When it was during the caliphate of Uthman and the number of people increased, he ordered the third adhan to be called and it was called in Al-Zawraa. The matter remained steadfast on that in 5745. Abu Amr Al-Adibi informed us that Abu Bakr Al-Ismaili informed us that Al-Hassan ibn Sufyan told us that Habban narrated from Ibn Al-Mubarak, from Yunus, who mentioned it in a similar manner except that he said, "Indeed, the adhan on Friday used to start when the Imam sat on the pulpit on Friday. Uthman ordered the third adhan on Friday, and the rest is the same."

I heard As-Saib bin Yazid, saying, "In the lifetime of Messenger of Allah ﷺ, and Abu Bakr and ʿUmar, the Adhan for the Jumua prayer used to be pronounced after the Imam had taken his seat on the pulpit. But when the people increased in number during the caliphate of ʿUthman, he introduced a third Adhan (on Friday for the Jumua prayer) and it was pronounced at Az-Zaura' and that new state of affairs remained so in the succeeding years.  

البخاري:٩١٦حَدَّثَنَا مُحَمَّدُ بْنُ مُقَاتِلٍ قَالَ أَخْبَرَنَا عَبْدُ اللَّهِ قَالَ أَخْبَرَنَا يُونُسُ عَنِ الزُّهْرِيِّ قَالَ

سَمِعْتُ السَّائِبَ بْنَ يَزِيدَ يَقُولُ إِنَّ الأَذَانَ يَوْمَ الْجُمُعَةِ كَانَ أَوَّلُهُ حِينَ يَجْلِسُ الإِمَامُ يَوْمَ الْجُمُعَةِ عَلَى الْمِنْبَرِ فِي عَهْدِ رَسُولِ اللَّهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ ؓ فَلَمَّا كَانَ فِي خِلاَفَةِ عُثْمَانَ ؓ وَكَثُرُوا أَمَرَ عُثْمَانُ يَوْمَ الْجُمُعَةِ بِالأَذَانِ الثَّالِثِ فَأُذِّنَ بِهِ عَلَى الزَّوْرَاءِ فَثَبَتَ الأَمْرُ عَلَى ذَلِكَ
