Imam Ja’far Sadiq  narrates from his ancestors that the Holy Prophet (s.a.w.s.) said, “The reward of offering a Prayer  in  Masjidun  Nabawi  is  equal  to  the  reward  of  ten thousand  Prayers  offered in  any  other  mosque  except  the Prayer offered in Masjidul Haraam whose reward is equal to the reward of a hundred thousand Prayers offered in another mosque.”
