حَدَّثَنَا حَجَّاجٌ حَدَّثَنَا شُعْبَةُ سَمِعْتُ أَبَا جَعْفَرٍ مُؤَذِّنَ الْعُرْبَانِ فِي مَسْجِدِ بَنِي هِلَالٍ عَنْ مُسْلِمٍ أَبِي الْمُثَنَّى مُؤَذِّنِ مَسْجِدِ الْجَامِعِ فَذَكَرَ هَذَا الْحَدِيثَ
مسند امام احمد بن حنبل · Hadith 5570
It was narrated that Ibn 'Umar said: At the time of the Messenger of Allah (PBUH) the adhaan was twice - Hajjaaj said: i.e, (each phrase) was repeated twice - and the iqaamah was once, except that he said: Qad qaamati's-salaah, cjad quamati s-salaah (Prayer is about to begin, Prayer is about to begin). When we heard the iqaamah we would do wudoo' then gp out to pray.
