Sahih al-Bukhari — Friday Prayer — Hadith No: 916
حَدَّثَنَا 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 صلى الله عليه وسلم وَأَبِي بَكْرٍ وَعُمَرَ ـ رضى الله عنهما ـ فَلَمَّا كَانَ فِي خِلاَفَةِ عُثْمَانَ ـ رضى الله عنه ـ وَكَثُرُوا، أَمَرَ عُثْمَانُ يَوْمَ الْجُمُعَةِ بِالأَذَانِ الثَّالِثِ، فَأُذِّنَ بِهِ عَلَى الزَّوْرَاءِ، فَثَبَتَ الأَمْرُ عَلَى ذَلِكَ.
Translation
Narrated Az-Zuhri:I heard As-Saib bin Yazid, saying, "In the lifetime of Allah's Messenger (ﷺ), and Abu Bakr and `Umar, 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 `Uthman, 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
