Sunan an-Nasa'i 4002
It was narrated that Sa'eed bin Jubair said:
"Abdur-Rahman bin Abi Laila told me to ask Ibn 'Abbas about two Verses: 'And whoever kills a believer intentionally, his recompense is Hell.' I asked him and he said: 'Nothing of this has been abrogated.' (And I asked him about the Verse): 'And those who invoke not any other ilah (god) along with Allah, or kill such person as Allah has forbidden, except by right,' he said: 'This was revealed concerning the people of Shirk.'"
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا مُحَمَّدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ مَنْصُورٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ أَمَرَنِي عَبْدُ الرَّحْمَنِ بْنُ أَبِي لَيْلَى أَنْ أَسْأَلَ ابْنَ عَبَّاسٍ، عَنْ هَاتَيْنِ الآيَتَيْنِ، ‏{‏ وَمَنْ يَقْتُلْ مُؤْمِنًا مُتَعَمِّدًا فَجَزَاؤُهُ جَهَنَّمُ ‏}‏ فَسَأَلْتُهُ فَقَالَ لَمْ يَنْسَخْهَا شَىْءٌ ‏.‏ وَعَنْ هَذِهِ الآيَةِ ‏{‏ وَالَّذِينَ لاَ يَدْعُونَ مَعَ اللَّهِ إِلَهًا آخَرَ وَلاَ يَقْتُلُونَ النَّفْسَ الَّتِي حَرَّمَ اللَّهُ إِلاَّ بِالْحَقِّ ‏}‏ قَالَ نَزَلَتْ فِي أَهْلِ الشِّرْكِ ‏.‏
