[Machine] The call to prayer was during the time of the Prophet Muhammad ﷺ , Abu Bakr, and Umar, two calls to prayer. Until the time of Uthman, when the number of people increased, he commanded to retain only the first call in Al-Zawra.
كَانَ الْأَذَانُ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ أَذَانَانِ حَتَّى كَانَ زَمَنُ عُثْمَانَ فَكَثُرَ النَّاسُ فَأَمَرَ بِالْأَذَانِ الْأَوَّلِ بِالزَّوْرَاءِ
[Machine] "The Adhan was pronounced twice during the time of the Prophet Muhammad ﷺ , Abu Bakr, and Umar. But when Uthman became the Caliph and the number of people increased, he commanded a caller to proclaim the Adhan for the Zawra'a prayer."
«كَانَ الْأَذَانُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ مَرَّتَيْنِ مَرَّتَيْنِ فَلَمَّا كَانَ عُثْمَانُ كَثُرَ النَّاسُ فَأَمَرْنَا مُنَادِيًا يُنَادِي عَلَى الزَّوْرَاءِ»
