Yahya related to me from Malik from Ibn Shihab that Salim ibn Abdullah said, "One of the companions of the Messenger of Allah, may Allah bless him and grant him peace, came into the mosque on the day of jumua and Umar ibn al Khattab was already giving the khutba. Umar said, 'What (kind of) time is this (to arrive)?' He said, Amir al- muminin, I returned from the market and heard the call to prayer, so I did no more than do wudu.' Umar said, 'You only did wudu as well? You know that the Messenger of Allah, may Allah bless him and grant him peace, used to tell people to do ghusl.' "
