"I asked Ibn 'Umar about the Adhan and he said: 'At the time of the Messenger of Allah ﷺ, the phrases of the Adhan were recited twice and the phrases of Iqamah once, except that you should say (the phrase) Qad qamat is-salah (prayer is about to begin)twice. When we heard 'prayer is about to begin' we would perform Wudu' and go out to pray.'"  

كَانَ الأَذَانُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ مَثْنَى مَثْنَى وَالإِقَامَةُ مَرَّةً مَرَّةً إِلاَّ أَنَّكَ إِذَا قُلْتَ قَدْ قَامَتِ الصَّلاَةُ قَالَهَا مَرَّتَيْنِ فَإِذَا سَمِعْنَا قَدْ قَامَتِ الصَّلاَةُ تَوَضَّأْنَا ثُمَّ خَرَجْنَا إِلَى الصَّلاَةِ  

The words of adhan were pronounced from the time of the Messenger of Allah ﷺ twice in pairs (i.e. four times) each, and the words of iqamah were pronounced once in pairs (twice each), except that the phrase "The time for prayer has come" would be pronounced twice. When we heard iqamah, we would perform ablution, and go out for prayer. Shu'bah said: I did not hear AbuJa'far narrating any other tradition except this one.  

إِنَّمَا كَانَ الأَذَانُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ مَرَّتَيْنِ مَرَّتَيْنِ وَالإِقَامَةُ مَرَّةً مَرَّةً غَيْرَ أَنَّهُ يَقُولُ قَدْ قَامَتِ الصَّلاَةُ قَدْ قَامَتِ الصَّلاَةُ فَإِذَا سَمِعْنَا الإِقَامَةَ تَوَضَّأْنَا ثُمَّ خَرَجْنَا إِلَى الصَّلاَةِ قَالَ شُعْبَةُ وَلَمْ أَسْمَعْ مِنْ أَبِي جَعْفَرٍ غَيْرَ هَذَا الْحَدِيثِ

When we heard 'prayer is about to begin' we would perform Wudu' and go out to pray.'" (Using translation from Nasāʾī 668)   

أَنَّهُ قَالَ كَانَ الْأَذَانُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ مَثْنَى مَثْنَى وَالْإِقَامَةُ مَرَّةً غَيْرَ أَنَّهُ كَانَ إِذَا قَالَ قَدْ قَامَتِ الصَّلَاةُ قَالَهَا مَرَّتَيْنِ فَإِذَا سَمِعْنَا الْإِقَامَةَ تَوَضَّأَ أَحَدُنَا وَخَرَجَ

When we heard iqamah, we would perform ablution, and go out for prayer. Shu'bah said: I did not hear AbuJa'far narrating any other tradition except this one. (Using translation from Abū Dāʾūd 510)   

سَمِعْتُ ابْنَ عُمَرَ يَقُولُ كَانَ الْأَذَانُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ مَرَّتَيْنِ مَرَّتَيْنِ وَالْإِقَامَةُ مَرَّةً مَرَّةً غَيْرَ أَنَّهُ يَقُولُ قَدْ قَامَتِ الصَّلَاةُ مَرَّتَيْنِ فَإِذَا سَمِعْنَا الْإِقَامَةَ تَوَضَّأْنَا ثُمَّ خَرَجْنَا إِلَى الصَّلَاةِ «»

«إِنَّمَا كَانَ الْأَذَانُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ مَرَّتَيْنِ وَالْإِقَامَةُ مَرَّةً غَيْرَ أَنَّهُ يَقُولُ قَدْ قَامَتِ الصَّلَاةُ قَدْ قَامَتِ الصَّلَاةُ فَإِذَا سَمِعْنَا الْإِقَامَةَ تَوَضَّأْنَا ثُمَّ جِئْنَا إِلَى الصَّلَاةِ»  

[Machine] I heard Abu Ja'far, the muezzin of the naked people, speaking in the mosque of Bani Hilal, talking about Muslim, the muezzin of the Grand Mosque, narrating from Ibn Umar that he said: "The Adhan during the time of the Messenger of Allah ﷺ used to be repeated twice, and the Iqamah was said only once. However, he used to say 'The prayer has been established, the prayer has been established'. So, whenever we heard the Iqamah, we would perform ablution and then go out for prayer." Shu'bah said: "I don't remember anything else from him except this narration."  

سَمِعْتُ أَبَا جَعْفَرٍ مُؤَذِّنَ الْعُرْيَانِ فِي مَسْجِدِ بَنِي هِلَالٍ يُحَدِّثُ عَنْ مُسْلِمٍ أَبِي الْمُثَنَّى مُؤَذِّنَ الْمَسْجِدِ الْجَامِعِ عَنِ ابْنِ عُمَرَ أَنَّهُ قَالَ إِنَّمَا كَانَ الْأَذَانُ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ مَرَّتَيْنِ مَرَّتَيْنِ وَالْإِقَامَةُ مَرَّةً غَيْرَ أَنَّهُ يَقُولُ «قَدْ قَامَتِ الصَّلَاةُ قَدْ قَامَتِ الصَّلَاةُ» فَكُنَّا إِذَا سَمِعْنَا الْإِقَامَةَ تَوَضَّأْنَا ثُمَّ خَرَجْنَا إِلَى الصَّلَاةِ قَالَ شُعْبَةُ لَا أَحْفَظُ عَنْهُ غَيْرَ هَذَا الْحَدِيثَ وَحْدَهُ
