Abdullah bin Anas reports in mursal form that the Prophet (peace and blessings be upon him) said: "Among the people of old, the most wretched was the one who hamstrung the she-camel (the miracle of Sayyiduna Salih), and O Ali! Among the later ones, the most wretched will be the one who strikes you with a spear." Then the Prophet (peace and blessings be upon him) also pointed towards the place of the spear.
