It is narrated from Hazrat Mu'adh (may Allah be pleased with him) that once he was riding behind the Noble Prophet (peace and blessings be upon him) on a donkey. The Noble Prophet (peace and blessings be upon him) called me by name and said, "O Mu'adh! Do you know what right Allah has over His servants?" I replied, "Allah and His Messenger know best." The Noble Prophet (peace and blessings be upon him) said, "(Allah's right over His servants is) that they worship Him alone and do not associate anything with Him." Then the Noble Prophet (peace and blessings be upon him) said, "Do you know what right the servants have over Allah if they do that?" The Noble Prophet (peace and blessings be upon him) said, "Their right is that Allah will not punish them."
