'Umar bin 'Ata' bin Abu Khuwar said that Nafi' bin Jubair sent him to al- Sa'ib the son of Namir's sister with a view to asking him about what he had seen in the prayer of Mu'awiyah. He said: Yes, I observed the Jumu'a prayer along with him in Maqsura and when the Imam pronounced salutation I stood up at my place and observed (Sunan rak'ahs). As he entered (the apartment) he sent for me and said: Do not repeat what you have done. Whenever you have observed the Jumu'a prayer, do not observe (Sunan prayer) till you, have talked or got out for the Messenger of Allah ( صلی اللہ علیہ وسلم ) had ordered us to do this and not to combine two (types of) prayers without talking or going out.

The same hadith is narrated on the authority of 'Umar bin Ata' but with this modification: When he (the Imam) pronounced salutation I stood up at my place. No mention was made of the Imam in it.
