What did Prophet Muhammad (saw) say about those who say, "None has the right to be worshipped but Allah"?
      Narrated Anas:                          The Prophet said, "Whoever said "None has the right to be worshipped      but Allah and has in his heart good (faith) equal to the weight of a      barley grain will be taken out of Hell. And whoever said: "None has      the right to be worshipped but Allah and has in his heart good (faith)     equal to the weight of a wheat grain will be taken out of Hell. And      whoever said, "None has the right to be worshipped but Allah and has      in his heart good (faith) equal to the weight of an atom will be taken     out of Hell."
