Al-Sa’ib ibn Yazid reported: The announcement of Friday prayer was first made when the Imam would sit upon the pulpit in the time of the Prophet, peace and blessings be upon him, as well as Abu Bakr and Umar, may Allah be pleased with them. In the time of Uthman, the number of people increased, so he added a third announcement at al-Zawra’, a place in the market of Medina.

عَنْ السَّائِبِ بْنِ يَزِيدَ قَالَ كَانَ النِّدَاءُ يَوْمَ الْجُمُعَةِ أَوَّلُهُ إِذَا جَلَسَ الْإِمَامُ عَلَى الْمِنْبَرِ عَلَى عَهْدِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَبِي بَكْرٍ وَعُمَرَ رَضِيَ اللَّهُ عَنْهُمَا فَلَمَّا كَانَ عُثْمَانُ رَضِيَ اللَّهُ عَنْهُ وَكَثُرَ النَّاسُ زَادَ النِّدَاءَ الثَّالِثَ عَلَى الزَّوْرَاءِ يعنى مَوْضِعٌ بِالسُّوقِ بِالْمَدِينَةِ
