Sunan Ibn Majah, Book 5, Hadith 1155 (In-Book) ⓘ

‘Abdur-Rahman bin Sa’d bin ‘Ammar bin Sad, the Mu’adh-dhin of the Prophet, said: “My father told me, narrating from his father, from his grandfather, that during the time of the Messenger of Allah, he used to call the Adhan on Fridays when the shadow was like a sandal strap.”

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ سَعْدِ بْنِ عَمَّارِ بْنِ سَعْدٍ، مُؤَذِّنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ حَدَّثَنِي أَبِي عَنْ أَبِيهِ عَنْ جَدِّهِ أَنَّهُ كَانَ يُؤَذِّنُ يَوْمَ الْجُمُعَةِ عَلَى عَهْدِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ إِذَا كَانَ الْفَىْءُ مِثْلَ الشِّرَاكِ ‏.‏
