وَعَنِ الْبَرَاءِ قَالَ: كَانَ رُكُوعُ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَسُجُودُهُ وَبَيْنَ السَّجْدَتَيْنِ وَإِذَا رَفَعَ مِنَ الرُّكُوعِ مَا خَلَا الْقيام وَالْقعُود قَرِيبا من السوَاء

Al-Bara,’ said that the bowing observed by the Prophet, his prostration, his sitting between the two sajdas, and when he raised his head after bowing, but not the standing and the sitting [when saying the shahada, were nearly equal.
