حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا شَبَابَةُ عَنْ إِسْرَائِيلَ عَنْ سِمَاکٍ عَنْ جَابِرِ بْنِ سَمُرَةَ قَالَ کَانَ بِلَالٌ يُؤَذِّنُ ثُمَّ يُمْهِلُ فَإِذَا رَأَی النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَدْ خَرَجَ أَقَامَ الصَّلَاةَ
سنن ابودوٗد · Hadith 537
Jabir bin Samurah said: Bilal would call the Adhan, then he used come to wait. When he would see that the prophet ﷺ had come out (of his house), he would pronounce the iqama.
