وَعَنْهُ أَيْضًا قَالَ: كَانَ الْأَذَانُ عَلَى عَهْدِ رَسُولِ اللَّهِ وَأَبِي بَكْرٍ وَعُمَرَ رَضِيَ اللَّهُ عَنْهُمَا أَذَانَيْنِ حَتَّى كَانَ زَمَنُ عُثْمَانَ فَكَثُرَ النَّاسُ فَأَمَرَ بِالْأَذَانِ الْأَوَّلِ بِالزَّوْرَاءِ
It is also narrated from Sayyiduna Sa’ib bin Yazid (may Allah be pleased with him) that during the times of the Messenger of Allah (peace and blessings be upon him), Sayyiduna Abu Bakr, and Sayyiduna Umar (may Allah be pleased with them both), there used to be two calls for Friday (the adhan and the iqamah). Then the era of Sayyiduna Uthman (may Allah be pleased with him) came, and when the number of people increased, Sayyiduna Uthman (may Allah be pleased with him) ordered an additional adhan to be given at the place called Zawra.
