Ibn Abbas (Allah be pleased with them) reported that Allah's Apostle (may peace be upon him) entered the Ka'ba, and in it there were six pillars, and he stood near a pillar and made supplication, but did not observe the prayer.

'Abdullah b. Zaid al-Ansari reported that the Messenger of Allah (may peace be upon him) went out to the place of prayer in order to offer prayer for rainfall. And when he intended to make supplication he faced Qibla and turned round his mantle.

Anas reported that the Apostle of Allah (may peace be upon him) was not accustomed to raice his hands in any supplication he made except when praying for rain. (He would then raise [his hands] high enough) that the whiteness of his armpits became visible. 'Abd al-A'la said that (he was in doubt whether it was) the whiteness of his armpit or armpits.

Ibn 'Umar reported that when the Messenger of Allah (may peace be upon him) sat for tashahhud he placed his left hand on his left knee. and his right hand on his right knee. and he raised his right finger, which is next to the thumb, making supplication in this way, and he stretched his left hand on his left knee.

Whenever the Prophet recited the Sura which contained the prostration of recitation he used to prostrate and then, we, too, would prostrate and some of us did not find a place for prostration.

The prostration in Sura-Sa`d is not amongst the compulsory prostrations, though I saw the Prophet prostrating on reciting it.

I saw Abu Huraira reciting Idha-Sama' un-Shaqqat and he prostrated during its recitation. I asked Abu Huraira, "Didn't I see you prostrating?" Abu Huraira said, "Had I not seen the Prophet prostrating, I would not have prostrated."

The first Sura in which a prostration was mentioned, was Sura An-Najm (The Star). Allah's Apostle prostrated (while reciting it), and everybody behind him prostrated except a man whom I saw taking a hand-full of dust in his hand and prostrated on it. Later I saw that man killed as an infidel, and he was Umaiya bin Khalaf.

When the Prophet recited a Sura that contained the prostration he would prostrate and we would do the same and some of us (because of the heavy rush) could not find a place for prostration.

`Umar bin Al-Khattab recited Surat-an-Nahl on a Friday on the pulpit and when he reached the verse of Sajda he got down from the pulpit and prostrated and the people also prostrated. The next Friday `Umar bin Al-Khattab recited the same Sura and when he reached the verse of Sajda he said, "O people! When we recite the verses of Sajda (during the sermon) whoever prostrates does the right thing, yet it is no sin for the one who does not prostrate." And `Umar did not prostrate (that day). Added Ibn `Umar "Allah has not made the prostration of recitation compulsory but if we wish we can do it."

(and he was not a liar) When Allah's Apostle said, "Sami`a l-lahu liman hamidah" none of us bent his back (for prostration) till the Prophet prostrated and then we would prostrate after him.

When the Prophet recited Surat As-Sajda and we were with him, he would prostrate and we also would prostrate with him and some of us (because of the heavy rush) would not find a place (for our foreheads) to prostrate on.

The Prophet recited Surat An-Najam and prostrated, and there was nobody who did not prostrate then except a man whom I saw taking a handful of pebbles, lifting it, and prostrating on it. He then said, "This is sufficient for me." No doubt I saw him killed as a disbeliever afterwards.

The prostration of Sa`d is not a compulsory one but I saw the Prophet prostrating while reciting it.

The time taken by the Prophet in prostrations, bowing, and the sitting interval between the two prostrations was about the same.
