The Slaughtered Bull
Scholars have said that seeing a bull slaughtered in a neighborhood or house and people dividing its meat may signify a calamity involving the death of an important man and the distribution of his wealth. It was also mentioned that the slaughter of animals like camels, rams, or calves in this manner carries the same interpretation. However, if the animal is slaughtered differently and its meat becomes ready for consumption, it is interpreted as lawful provision and wealth.
