حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ سَعْدِ بْنِ عَمَّارِ بْنِ سَعْدٍ، مُؤَذِّنِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ حَدَّثَنِي أَبِي عَنْ أَبِيهِ عَنْ جَدِّهِ أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ كَانَ يُكَبِّرُ فِي الْعِيدَيْنِ فِي الأُولَى سَبْعًا قَبْلَ الْقِرَاءَةِ وَفِي الآخِرَةِ خَمْسًا قَبْلَ الْقِرَاءَةِ ‏.‏
