Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "On the Day of Resurrection, the most severe punishment will be for these people: the man whom a prophet killed, or the one who killed a prophet, a misguided leader, and the one who mutilates the most among those who mutilate."
