What did the Prophet Muhammad (saw) tell the man who entered the mosque while he was delivering the Khutba on a Friday?
 Narrated Jabir bin `Abdullah:                     A person entered the mosque while the Prophet was delivering the Khutba on a Friday. The Prophet said to him, "Have you prayed?" The man replied in the negative. The Prophet said, "Get up and pray two rak`at."
