The Sunnah Regarding The Adhan
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا أَبُو دَاوُدَ، حَدَّثَنَا شَرِيكٌ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، قَالَ كَانَ بِلاَلٌ لاَ يُؤَخِّرُ الأَذَانَ عَنِ الْوَقْتِ وَرُبُّمَا أَخَّرَ الإِقَامَةَ شَيْئًا .
It was narrated that Jabir bin Samurah said: "Bilal did not delay the Adhan from its proper time, but he sometimes delayed the Iqamah a little."
