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."

حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا مَنْصُورٌ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ سَأَلْتُ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ عَنْ قَوْلِهِ تَعَالَى فَجَزَاؤُهُ جَهَنَّمُ قَالَ لاَ تَوْبَةَ لَهُ. وَعَنْ قَوْلِهِ جَلَّ ذِكْرُهُ لاَ يَدْعُونَ مَعَ اللَّهِ إِلَهًا آخَرَ قَالَ كَانَتْ هَذِهِ فِي الْجَاهِلِيَّةِ.
