Sahih al-Bukhari 825
Sahih al-Bukhari · Book 10: Call to Prayers (Adhaan) · Saying Takbir on rising from the two prostrations
Narrated Sa`id bin Al-Harith:
حَدَّثَنَا يَحْيَى بْنُ صَالِحٍ ، قَالَ حَدَّثَنَا فُلَيْحُ بْنُ سُلَيْمَانَ ، عَنْ سَعِيدِ بْنِ الْحَارِثِ ، قَالَ صَلَّى لَنَا أَبُو سَعِيدٍ فَجَهَرَ بِالتَّكْبِيرِ حِينَ رَفَعَ رَأْسَهُ مِنَ السُّجُودِ، وَحِينَ سَجَدَ، وَحِينَ رَفَعَ، وَحِينَ قَامَ مِنَ الرَّكْعَتَيْنِ وَقَالَ هَكَذَا رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم .
Abu Sa`id led us in the prayer and said the Takbir aloud on arising from the prostration, and on prostrating, on rising again, and on getting up from the second rak`a. Abu Sa`id said, "I saw the Prophet doing the same."
