Ibn Mas'ud (May Allah be pleased with him) reported:
The Prophet (ﷺ) said, "The first son of Adam* takes a share of the guilt of every one who murders another wrongfully because he was the initiator of committing murder".[Al-Bukhari and Muslim].* The son of Adam in the Hadith is said to be Qabil. Allah tells us about his story in Surat Al-Ma'idah (The Table spread with Food). Verses 27-31.
