Narrated Said bin Jubair:
I asked Ibn ‘Abbas about Allah’s saying:–
‘.. this reward is Hell Fire.’ (4.93) He said, “No repentance is accepted from him (i.e. the murderer of a believer).” I asked him regarding the saying of Allah: ‘Those who invoke not with Allah any other god.’ …(25.68)
He said, “This Verse was revealed concerning the pagans of the pre-lslamic period.”
