Malik related to me, "Ibn Shihab did notthink and nor do I, that there is a generally agreed on way of doingthings regarding a piercing wound in any of the organs or limbs of thebody, but I think that there is ijtihad in the case. The imam usesijtihad in it, and there is no generally agreed on way of doing thingsin our community about it."Malik said, "What is done in ourcommunity about the wound to the brain and the wound which splintersthe bone, and the wound that bares the bone is that they apply only tothe head and face. Whatever of that occurs in the body only hasijtihad in it."Malik said, "I do not think the lower jaw andthe nose are part of the head in their injury because they areseparate bones, and except for them the head is one bone."
