[Machine] "That the first Adhan was when the Imam sits on the pulpit on the Day of Friday during the time of the Messenger of Allah ﷺ , Abu Bakr, and Omar."
«أَنَّ الْأَذَانَ كَانَ أَوَّلُهُ حِينَ يَجْلِسُ الْإِمَامُ عَلَى الْمِنْبَرِ يَوْمَ الْجُمُعَةِ فِي عَهْدِ رَسُولِ اللهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ ؓ»
During the time of the Prophet ﷺ and Abu Bakr and 'Umar the call to the Friday prayer was first made at the time when the imam was seated on the pulpit (for giving the sermon). When the time of 'Uthman came, and the people became abundant, 'Uthman ordered to make a third call to the Friday prayer. It was made on al-Zaura' (a house in Medina). The rule of action continued to the same effect. (Using translation from Abū Dāʾūd 1087)
«أَنَّ الْأَذَانَ كَانَ أَوَّلُهُ حِينَ يَجْلِسُ الْإِمَامُ عَلَى الْمِنْبَرِ يَوْمَ الْجُمُعَةِ فِي عَهْدِ رَسُولِ اللهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ فَلَمَّا كَانَ خِلَافَةُ عُثْمَانَ كَثُرَ النَّاسُ وَأَمَرَ عُثْمَانُ بْنُ عَفَّانَ يَوْمَ الْجُمُعَةِ بِالْأَذَانِ الثَّالِثِ فَأُذِّنَ بِهِ عَلَى الزَّوْرَاءِ»
