Bowing - Section 1
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 [during recitation of the Qur’an] and the sitting [when saying the shahada, were nearly equal. (Bukhari and Muslim.)
