Silsilat al-Ahadith al-Sahihah

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