Mu'ãdh ibne-Anas Juhaní (Ra) narrates that Rasúlullãh (saw) said: He who remains sitting in his place of Salãt, after offering his Fajr Salãt, till he offers the forenoon Salãt, saying nothing except what is good, his sins will be forgiven, even if they are more than the foam of the sea.
(Abu Dãwúd)
