Hadrat Jabir (Radhiallahu’anhu) narrated that some angels came the Holy Prophet (Sallallahu’alaihi wa Sallam) in such a condition that he was asleep. The angels said, “There is a similitude for this friend of yours ;therefore mention it ,” On this some of them said , “ He is asleep ,” While others said , “ His eye are closed but his heart is awakened,” Then the angels remark , “His similitude is like the person who built a house and sent a messenger to invite people on a feast in that house . Whosoever accepted the invitation , entered the house and partook from the feast . While whoever did not accepted the invitation, was neither able to enter the house nor to enjoy the feast.” Then some of the angels said, “ Explain it so that he (i.e . the Holy Prophet) may understand it” .On this some of them (again)said , “He is asleep while others said “ His eye are closed but his heart is awakened,” Then the angels explained, “The house means the Paradise (al-jannah) and the messenger is Muhammad (Sallallahu’alaihi wa Sallam) “Whosoever obeyed Muhammad ,(he actually) obey Allah ;and whoever disobeyed Muhammad (he actually) disobeyed Allah .(And ) Muhammad is the sign of distinction ( between the believer and a non-believer i.e. those who are obedient to him are the Believers while those are disobedient to him are the non-believer.
