A Sultan's or Imam's Wound
Scholars have said that if a Sultan or Imam dreams of a wound to their head, tearing their skin and bone, it might indicate a long life. If the bone is crushed, it might signify the defeat of their army. Wounds in different body parts also carry implications related to the increase of their army, dominion, wealth, clan, lifespan, or the rectitude of their affairs and stability of their wealth.
