“Ibn Abbas was asked about one who kills a believer deliberately, then repents, believes, does righteous deeds and follows true guidance. He said: 'Woe to him can there be any guidance for him? I heard your Prophet ﷺ say: “The killer and his victim will be brought on the day of Resurrection, with slain holding onto the head of his killer, saying: 'O Lord, ask this one, why did he kill me?” By Allah (SWT), Allah (SWT) the Mighty and Sublime revealed it to your Prophet ﷺ then He did not abrogate it after He revealed it.”
سَمِعْتُ نَبِيَّكُمْ ﷺ يَقُولُ يَجِيءُ الْقَاتِلُ وَالْمَقْتُولُ يَوْمَ الْقِيَامَةِ مُتَعَلِّقٌ بِرَأْسِ صَاحِبِهِ يَقُولُ رَبِّ سَلْ هَذَا لِمَ قَتَلَنِي وَاللَّهِ لَقَدْ أَنْزَلَهَا اللَّهُ ﷻ عَلَى نَبِيِّكُمْ ثُمَّ مَا نَسَخَهَا بَعْدَ مَا أَنْزَلَهَا
