عَنْ سَعِيدِ بْنِ الْحَارِثِ بْنِ الْمُعَلَّى قَالَ: صَلَّى لَنَا أَبُو سَعِيدٍ الْخُدْرِيُّ فَجَهَرَ بِالتَّكْبِيرِ حِينَ رَفَعَ رَأْسَهُ مِنَ السُّجُودِ وَحِينَ سَجَدَ وَحِينَ رَفَعَ مِنَ الرَّكْعَتَيْنِ وَقَالَ: هَكَذَا رَأَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ. رَوَاهُ الْبُخَارِيُّ
Translation
‘Ikrima said

I prayed behind an old man in Mecca and he said the takbir twenty-two times. When I said to Ibn ‘Abbas that the man was a fool, he replied, “I am surprised at you. It was the sunna of Abul Qasim.’’* *This is the Prophet’s kunya.Bukhari transmitted it.
