`Umar b. `Ata' b. Abu Khuwar said that Nafi` b. Jubair sent him to al- Sa'ib the son of Namir's sister to ask him about what he had seen in the prayer of Mu`awiya. 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 gone 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.
