Quran Al-Baqarah 84, 85, 86

And (remember) when We took your covenant (saying) : Shed not the blood of your (people ) , nor turn out your own people from their dwellings. Then , (this) you ratified and (to this) you bear witness. After this , it is who kill one another and drive out a party of you from their home , assist (their enemies) against them , in sin and transgression .And if they come to you as captives, you ransom them , although their expulsion was forbidden to you . Then do you believe in a part of the Scripture and reject the rest ? Then what is the recompense of those who do so among you , except disgrace in the life of this world , and on the Day of Resurrection they shall be consigned to the most grievous torment . And Allah is not unaware of what you do . Those are they who have bought yhe life of this world at the price of the Hereafter . Their torment shall not be lightened nor shall they be helped.
