Sa'id b. Jubair reported:
Abd al Rahman b. Abzi commanded me that I should ask Ibn 'Abbas about these two verses:" He who slays a believer intentionally his requital shall be Hell where he would abide for ever" (4:92). So, I asked him and he said: Nothing has abrogated it. And as for this verse:" And they who call not upon another god with Allah and slay not the soul which Allah has forbidden, except in the cause of justice" (25:68), he (Ibn Abbas) said: This has been revealed in regard to the polytheists."
