[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
