The bowing, the prostrations, the period of standing after bowing and the interval between the two prostrations of the Prophet (ﷺ) used to be equal in duration .
Sahih al-Bukhari Book 10, Hadith 196
← Previous Hadith Anas used to demonstrate to us the prayer of the Prophet (ﷺ) and while demonstrating, he used to raise his head from bowing and stand so long that we would say that he had forgotten (the prostration).

Sahih al-Bukhari Book 10, Hadith 195 Next Hadith → Abu Qilaba said, "Malik bin Huwairith used to demonstrate to us the prayer of the Prophet (ﷺ) at times other than that of the compulsory prayers. So (once) he stood up for prayer and performed a perfect Qiyam (standing and reciting from the Holy Qur'an) and then bowed and performed bowing perfectly; then he raised his head and stood straight for a while." Abu Qilaba added, "Malik bin Huwairith in that demonstration prayed like this Sheikh of ours, Abu Yazid." Abu, Yazid used to sit (for a while) on raising his head from the second prostration before getting up.
