Mishkat al-Masabih 4 Prayer كتاب الصلاة 234

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

Sa’id b. al-Harith b. al-Mu‘alla said that Abu Sa’id al-Khudri led them in prayer and said the takbir loudly when he raised his head after the prostration, when he prostrated himself, and when he rose at the end of two rak’as , and he said, “Thus did I see the Prophet do.” Bukhari transmitted it.
