Sunan an-Nasa'i, Book 12, Hadith 37 (In-Book) ⓘ

It was narrated from Al-Bara' bin 'Azib that: The bowing of the Messenger of Allah, and when he raised his head from bowing, and his prostration, and the time between the two prostration, were almost equal in length.

أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا ابْنُ عُلَيَّةَ، قَالَ أَنْبَأَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى، عَنِ الْبَرَاءِ بْنِ عَازِبٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ رُكُوعُهُ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَسُجُودُهُ وَمَا بَيْنَ السَّجْدَتَيْنِ قَرِيبًا مِنَ السَّوَاءِ ‏.‏
