“The Prophet ﷺ used to say the Takbir between the two sermons and he used to say the Takbir a great deal in the sermon of ‘Eid.”  

ابن ماجة:١٢٨٧ – حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ سَعْدِ بْنِ عَمَّارِ بْنِ سَعْدٍ الْمُؤَذِّنِ حَدَّثَنِي أَبِي عَنْ أَبِيهِ عَنْ جَدِّهِ قَالَ

كَانَ النَّبِيُّ ﷺ يُكَبِّرُ بَيْنَ أَضْعَافِ الْخُطْبَةِ يُكْثِرُ التَّكْبِيرَ فِي خُطْبَةِ الْعِيدَيْنِ

[Machine] The Messenger of Allah ﷺ used to start with prayer before the sermon, and he liked to make Takbir (saying "Allahu Akbar") between the segments of the sermon.  

البيهقي:٦٢١٤ – أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ ثنا أَبُو بَكْرِ بْنُ إِسْحَاقَ الْفَقِيهُ أنبأ الْحَسَنُ بْنُ عَلِيِّ بْنِ زِيَادٍ ثنا إِبْرَاهِيمُ بْنُ مُوسَى ثنا عَبْدُ الرَّحْمَنِ بْنُ سَعْدِ بْنِ عَمَّارِ بْنِ سَعْدٍ الْمُؤَذِّنُ أَخْبَرَنِي عَبْدُ اللهِ بْنُ مُحَمَّدٍ وَعَمَّارُ بْنُ حَفْصٍ وَعُمَرُ بْنُ حَفْصٍ عَنْ آبَائِهِمْ عَنْ أَجْدَادِهِمْ

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَبْدَأُ بِالصَّلَاةِ قَبْلَ الْخُطْبَةِ وَكَانَ يُحِبُّ أَنْ يُكَبِّرَ التَّكْبِيرَ بَيْنَ أَضْعَافِ الْخُطْبَةِ
