`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."

The Messenger of Allah (saws) recited surah Sad on the pulpit. When he reached the place of prostration (in the surah), he descended and prostrated himself and the people prostrated with him. When the next day came, he recited it. When he reached the place of prostration (in the surah), the people became ready for prostration. Thereupon the Messenger of Allah (saws) said: This is the repentance of a Prophet ; but I saw you being ready for prostration. So he descended and prostrated himself and the people prostrated along with him.

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.

Yahya related to me from Malik from Abdullah ibn Yazid, the mawla of al Aswad ibn Sufyan, from Abu Salama ibn Abd ar Rahman that Abu Hurayra recited al-Inshiqaq (Sura 84) to them and prostrated in it. When he had finished he told them that the Messenger of Allah, may Allah bless him and grant him peace, had prostrated in it.

In the year of Conquest the Messenger of Allah (saws) recited a verse at which a prostration should be made and all the people prostrated themselves. Some were mounted, and some were prostrating themselves on the ground, and those who were mounted prostrated themselves on their hands.

Yahya related to me from Malik from Hisham ibn Urwa from his father that Umar ibn al-Khattab once recited a piece of Qur'an requiring a prostration while he was on the mimbar on the day of jumua, and he came down and prostrated, and everyone prostrated with him. Then he recited it again the next jumua and everybody prepared to prostrate but he said, "At your ease. Allah has not prescribed it for us, unless we wish." He did not prostrate, and he stopped them from prostrating.

The Prophet recited Suratan-Najm (103) at Mecca and prostrated while reciting it and those who were with him did the same except an old man who took a handful of small stones or earth and lifted it to his forehead and said, "This is sufficient for me." Later on, I saw him killed as a non-believer.

The Prophet recited Surat-an-Najm (53) and prostrated while reciting it and all the people prostrated and a man amongst the people took a handful of stones or earth and raised it to his face and said, "This is sufficient for me. Later on I saw him killed as a non-believer."

The Prophet recited Surat-an-Najm and then prostrated himself, and all who were with him prostrated too. But an old man took a handful of dust and touched his forehead with it saying, "This is sufficient for me." Later on I saw him killed as an infidel.
