Narrated Rabi'a:

'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.

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."

Narrated Abu Rafi:

I offered the 'Isha' prayer behind Abu Huraira and he recited Idhas-Sama' Un-Shaqqat, and prostrated. I said, "What is this?" Abu Huraira said, "I prostrated behind Abu-l-Qasim and I will do the same till I meet him."

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.
