question #3 Sahih al-Bukhari 4764, Book 65, Hadith 286 : What are the implications of invoking other gods alongside Allah in Islamic belief?

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

‘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.”
