The Book of Mosques and Places of Prayer
وَحَدَّثَنِي سَلَمَةُ بْنُ شَبِيبٍ، حَدَّثَنَا الْحَسَنُ بْنُ أَعْيَنَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا سِمَاكُ بْنُ حَرْبٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، قَالَ كَانَ بِلاَلٌ يُؤَذِّنُ إِذَا دَحَضَتْ فَلاَ يُقِيمُ حَتَّى يَخْرُجَ النَّبِيُّ صلى الله عليه وسلم فَإِذَا خَرَجَ أَقَامَ الصَّلاَةَ حِينَ يَرَاهُ .Jabir b. Samura reported:Bilal summoned to prayer as the sun declined but did not pronounce Iqama till the Messenger of Allah (ﷺ) came out and the Iqama was pronounced on seeing him
From Sahih Muslim, whose reports the scholars accept as authentic.
