حَدَّثَنَا يَحْيَی بْنُ بُکَيْرٍ قَالَ حَدَّثَنَا اللَّيْثُ عَنْ عُقَيْلٍ عَنْ ابْنِ شِهَابٍ أَنَّ السَّائِبَ بْنَ يَزِيدَ أَخْبَرَهُ أَنَّ التَّأْذِينَ الثَّانِيَ يَوْمَ الْجُمُعَةِ أَمَرَ بِهِ عُثْمَانُ بْنُ عَفَّانَ رَضِيَ اللَّهُ عَنْهُ حِينَ کَثُرَ أَهْلُ الْمَسْجِدِ وَکَانَ التَّأْذِينُ يَوْمَ الْجُمُعَةِ حِينَ يَجْلِسُ الْإِمَامُ
صحیح بخاری · Hadith 915
Narrated As-Sa'ib bin Yazid I: `Uthman bin `Affan introduced the second Adhan on Fridays when the number of the people in the mosque increased. Previously the Adhan on Fridays used to be pronounced only after the Imam had taken his seat (on the pulpit).
