Praying After The Friday Prayer Sunan Abi Dawud 1129
Translation
'Umar b. 'Ata' b. Abu al-Khuwar said that Nafi' b. Jubair sent him to al-Sa'ib b. Yazid b. Ukht Namir to ask him about something Mu'awiyyah had seen him do in prayer. He said
I offered the Friday prayer along with him in the enclosure. When I uttered the salutation, I stood up in my place and prayed. When he entered, he sent a message to me, saying: Do not repeat what you did. When you pray the Friday prayer, do not join it to another prayer until you speak or go out, for the Prophet of Allah (ﷺ) commanded us regarding that: that no prayer should be joined to another until one speaks or goes out.
