الحاكم:١١١٦فَحَدَّثَنَا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ أَنْبَأَ الْعَبَّاسُ بْنُ الْوَلِيدِ بْنِ مَزْيَدٍ ثنا أَبِي قَالَ سَمِعْتُ الْأَوْزَاعِيَّ وَسُئِلَ عَنِ التَّكْبِيرِ يَوْمَ عَرَفَةَ فَقَالَ

«يُكَبَّرُ مِنْ غَدَاةِ عَرَفَةَ إِلَى آخِرِ أَيَّامِ التَّشْرِيقِ كَمَا كَبَّرَ عَلِيٌّ وَعَبْدُ اللَّهِ» آخِرُ كِتَابِ الْعِيدَيْنِ
