Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Whoever catches one rak'ah of Jumu'ah should complete it by adding another rak'ah to it." Janab Usamah says: I heard both the people of the gathering, Qasim bin Muhammad and Salim, saying that this has reached us.
