Sayyiduna Ibn Umar (may Allah be pleased with them both) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever mutilates his brother (disfiguring him by cutting off his limbs), upon him is the curse of Allah, of the angels and of all the people."
(Al-Asamm refers to Yazid bin Hurmuz, and Allah knows best.)
