BAYHAQI 2552:
from ʿĀʾishah —
[Machine] She said, "The Messenger of Allah ﷺ used to begin the prayer by saying the takbeer. He mentioned a narration in which it was stated that he, when bowing, would not lower his head nor straighten it, but between that, he mentioned the narration."
البيهقي ٢٥٥٢:
عن عاءشه —
قَالتْ كَانَ رَسُولُ اللهِ ﷺ يَفْتَتِحُ الصَّلَاةَ بِالتَّكْبِيرِ فَذَكَرَ الْحَدِيثَ وَفِيهِ وَكَانَ إِذَا رَكَعَ لَمْ يُشْخِصْ رَأْسَهُ وَلَمْ يُصَوِّبْهُ وَلَكِنْ بَيْنَ ذَلِكَ وَذَكَرَ الْحَدِيثَ
