Narrated Sa`id 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.‏
