Sunan Ibn Majah, Book 5, Hadith 1189 (In-Book) ⓘ

It was narrated that Sa’ib bin Yazid said: “The Messenger of Allah had only one Mu’adh-dhin. When he came out he would give the Adhan and when he came down (from the pulpit) he would give the Iqamah. Abu Bakr and ‘Umar did likewise, but when ‘Uthman (became caliph) the numbers of people had increased, he added the third call from atop a house in the marketplace that was called Zawra’. When he came out (the Mu’adh-dhin) would call the Adhan, and when he came down from the pulpit, he would call the Iqamah.

حَدَّثَنَا يُوسُفُ بْنُ مُوسَى الْقَطَّانُ، حَدَّثَنَا جَرِيرٌ، ح وَحَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَعِيدٍ، حَدَّثَنَا أَبُو خَالِدٍ الأَحْمَرُ، جَمِيعًا عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ، عَنِ الزُّهْرِيِّ، عَنِ السَّائِبِ بْنِ يَزِيدَ، قَالَ مَا كَانَ لِرَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ إِلاَّ مُؤَذِّنٌ وَاحِدٌ فَإِذَا خَرَجَ أَذَّنَ وَإِذَا نَزَلَ أَقَامَ وَأَبُو بَكْرٍ وَعُمَرُ كَذَلِكَ فَلَمَّا كَانَ عُثْمَانُ وَكَثُرَ النَّاسُ زَادَ النِّدَاءَ الثَّالِثَ عَلَى دَارٍ فِي السُّوقِ يُقَالُ لَهَا الزَّوْرَاءُ فَإِذَا خَرَجَ أَذَّنَ وَإِذَا نَزَلَ أَقَامَ ‏.‏
