What special ability did God give Joseph?

Answer: Interpreting dreams

Joseph said, "Don't interpretations belong to God?" and told Pharaoh, "God will give Pharaoh a sound answer."

““We both had dreams,” they replied, “but there is no one to interpret them.” Then Joseph said to them, “Don’t interpretations belong to God? Tell me your dreams.” “I myself cannot do it,” Joseph replied, “but God will give Pharaoh a sound answer.””— Genesis 40:8, 41:16 (BSB)
