Musannaf Ibn Abi Shayba 21:613

Abu Sa’id, the freed slave of Abu Usayd, said: I got married while I was a slave, so I invited a group of the companions of the Prophet, may Allah bless him and grant him peace, among them Ibn Mas’ud, Abu Dharr, and Hudhayfah. They taught me, saying: "When your wife enters upon you, pray two rak'ahs, then ask Allah for the good of what has entered upon you, then seek refuge in Him from its evil, then [attend to] your affair and the affair of your wife."
