'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.
