After this it is ye , the same people , who slay among yourselves , and banish a party of you from their homes ; assist ( Their enemies ) against them , in guilt and rancour ; and if they come to you as captives , ye ransom them , though it was not lawful for you to banish them . Then is it only a part of the Book that ye believe in , and do ye reject the rest ? but what is the reward for those among you who behave like this but disgrace in this life ? - and on the Day of Judgment they shall be consigned to the most grievous penalty .
