Read the English translation first, with the original Arabic directly underneath.
Narrated `Abdullah:
Allah's Messenger (ﷺ) said, "Whenever a person is murdered unjustly, there is a share from the burden of the crime on the first son of Adam for he was the first to start the tradition of murdering."
لاَ تُقْتَلُ نَفْسٌ ظُلْمًا إِلاَّ كَانَ عَلَى ابْنِ آدَمَ الأَوَّلِ كِفْلٌ مِنْ دَمِهَا، لأَنَّهُ أَوَّلُ مَنْ سَنَّ الْقَتْلَ
