"I said to Ibn 'Abbas: 'Can a person, who killed a believer intentionally, repent?' He said: 'No.' I recited the Verse from Al-Furqan to him: '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 Verse was revealed in Makkah and was abrogated by a Verse that was revealed in Al-Madinah: 'And whoever kills a believer intentionally, his recompense is Hell.'"  

قُلْتُ لاِبْنِ عَبَّاسٍ هَلْ لِمَنْ قَتَلَ مُؤْمِنًا مُتَعَمِّدًا مِنْ تَوْبَةٍ قَالَ لاَ وَقَرَأْتُ عَلَيْهِ الآيَةَ الَّتِي فِي الْفُرْقَانِ { وَالَّذِينَ لاَ يَدْعُونَ مَعَ اللَّهِ إِلَهًا آخَرَ وَلاَ يَقْتُلُونَ النَّفْسَ الَّتِي حَرَّمَ اللَّهُ إِلاَّ بِالْحَقِّ } قَالَ هَذِهِ آيَةٌ مَكِّيَّةٌ نَسَخَتْهَا آيَةٌ مَدَنِيَّةٌ { وَمَنْ يَقْتُلْ مُؤْمِنًا مُتَعَمِّدًا فَجَزَاؤُهُ جَهَنَّمُ }
