Narrated 'Amr bin Dinar:from Ibn 'Abbas that the Prophet (ﷺ) said: "On the Day of Judgement, the murdered will come with the murderer's scalp and his head in his hand, and his jugular vein flowing blood saying: 'O Lord! This one killed me!' Until he comes close to the Throne." So they mentioned repentance to Ibn 'Abbas, and he recited this Ayah: And whoever kills a believer intentionally then his recompense is Hell (4:93). He said: "This Ayah was not abrogated nor (its ruling) replaced so from where is his repentance?
