حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى وَمُحَمَّدُ بْنُ بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ مَنْصُورٍ عَنْ سَعِيدِ بْنِ جُبَيْرٍ قَالَ أَمَرَنِى عَبْدُ الرَّحْمَنِ بْنُ أَبْزَى أَنْ أَسْأَلَ ابْنَ عَبَّاسٍ عَنْ هَاتَيْنِ الآيَتَيْنِ (وَمَنْ يَقْتُلْ مُؤْمِنًا مُتَعَمِّدًا فَجَزَاؤُهُ جَهَنَّمُ خَالِدًا فِيهَا) فَسَأَلْتُهُ فَقَالَ لَمْ يَنْسَخْهَا شَىْءٌ. وَعَنْ هَذِهِ الآيَةِ (وَالَّذِينَ لاَ يَدْعُونَ مَعَ اللَّهِ إِلَهًا آخَرَ وَلاَ يَقْتُلُونَ النَّفْسَ الَّتِى حَرَّمَ اللَّهُ إِلاَّ بِالْحَقِّ) قَالَ نَزَلَتْ فِى أَهْلِ الشِّرْكِ.

It was narrated that Sa'd bin Jubair, may Allah be pleased with him, said: "Abdur-Rahman bin Abza told me to ask Ibn 'Abbas for him about these two Verses: "And whoever kills a believer intentionally, his recompense is Hell to abide therein..." I asked him, and he said: 'It has not been abrogated by anything.' And about this Verse: "And those who invoke not any other ilah (god) along with Allah, nor kill such person as Allah has forbidden, except for just cause..." He said: 'It was revealed concerning the people of Shirk."'
