Eating Ox and Calf Meat
Interpreters mention that whoever dreams of eating ox meat may indicate going to a ruler. As for seeing oneself eating a fat, roasted calf, it is interpreted as a great and swift good omen, signifying sustenance, fertility, and salvation from fear, with the value of the omen depending on the calf's fatness. It has been reported that cooked beef symbolizes great grace received by the dreamer, requiring gratitude to God.
