Abu Humaid said: The Prophet (SAW) rose (from bowing) and stood straight till all the vertebra of his spinal column came to a natural position. [Taken from Chapter 127, volume 1 of the 9-volume version of Bukhari, translated by Muhsin Khan and published by Darussalam]
Anas used to demonstrate to us the prayer of the Prophet 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).
The bowing, the prostrations, the period of standing after bowing and the interval between the two prostrations of the Prophet used to be equal in duration.
Abu Qilaba said, “Malik bin Huwairith used to demonstrate to us the prayer of the Prophet 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.
In simple words, namaz mein takrein maarney se parhez kerein.
Give time to your body to settle after each change in position. It’s really important if you wish to bring khushoo` to your Salah.
The Prophet used to pray a short prayer (in congregation) but used to offer it in a perfect manner.
Perfection of prayer. What is it? Establishing it, praying regularly and on time, performing all sujud, ruku`, qiyaam etc. properly, and giving each position ‘time’. We get to know from different narrations the way that Prophet (SAW) used to pray. His each and every action and move have been recorded in Ahadith (awesome observation of Companions!).
Companions say that the Prophet (SAW) used to perform the Salah in a perfect manner. He used to give each position time. When in ruku`, he would stay in that position for a while, make the ruku` last long, and then change his position. Similarly, when getting back up from the ruku` position, he would give it time, let the body settle in standing position, and then go down for sajdah. Get it?
Now you check your Salah. Or let somebody else check it for you and point out your mistakes. Because if you don’t offer your Salah ‘perfectly’, you’re not following the Sunnah. And what good is all the effort then?
Annnnyway, check the speed of your Salah. Even if your prayer is short, do you perform it ‘perfectly’? Do you give Salah its due right? Or do you just do some exercise five times a day everyday?
