Yet ye it is who slay each other and drive out a party of your people from their homes , supporting one another against them by sin and transgression ? - and if they came to you as captives ye would ransom them , whereas their expulsion was itself unlawful for you - Believe ye in part of the Scripture and disbelieve ye in part thereof ? And what is the reward of those who do so save ignominy in the life of the world , and on the Day of Resurrection they will be consigned to the most grievous doom .
