It was narrated that Ibn 'Umar said:

"When 'Umar bin Khattab was appointed caliph, he addressed the people and said: 'The Messenger of Allah permitted temporary marriage for us three times, then he forbade it. By Allah, If I hear of any married person entering a temporary marriage, I will stone him to death, unless he can bring me four witnesses who will testify that the Messenger of Allah, allowed it after he forbade it'."

It was narrated from Ibrahim bin Abu Musa:

“Abu Musa Al-Ash’ari used to issue rulings concerning Tamattu’. Then a man said to him: ‘Withhold some of your rulings, for you do not know what the Commander of the Believers has introduced into the rites after you.’ (Abu Musa said:) ‘Then when I met him later on, I asked him.’ ‘Umar said: ‘I know that the Messenger of Allah (s.a.w.a.) and his Companions did it, but I did not like that people should lie with their wives in the shade of the Arak trees and then go out for Hajj with their heads dripping,’ (i.e. due to the bath after sexual relations).”

It was narrated that Abu Dharr said:

“Tamattu’ in Hajj was for the Companions of Muhammad (s) specifically.”
