Musnad Uthman ibn Affan
Musnad Ahmad 540
It was narrated that Moosa bin Talha said:
I Heard ‘Uthman bin ‘Affan (رضي الله عنه) when he was on the minbar and the mu’adhdhin was giving the iqamah (call immediately preceding the prayer), asking the people about their news and business.
حَدَّثَنَا هُشَيْمُ بْنُ بُشَيْرٍ، إِمْلَاءً قَالَ أَنْبَأَنَا مُحَمَّدُ بْنُ قَيْسٍ الْأَسَدِيُّ، عَنْ مُوسَى بْنِ طَلْحَةَ، قَالَ سَمِعْتُ عُثْمَانَ بْنَ عَفَّانَ، رَضِيَ اللَّهُ عَنْهُ وَهُوَ عَلَى الْمِنْبَرِ وَالْمُؤَذِّنُ يُقِيمُ الصَّلَاةَ وَهُوَ يَسْتَخْبِرُ النَّاسَ يَسْأَلُهُمْ عَنْ أَخْبَارِهِمْ وَأَسْعَارِهِمْ‏.‏
