2 verses have
sufficient
in Edition Clear Qur'an by Talal Itani / Yunus (Jonas)

10:29“God is sufficient witness between us and you. We were unaware of your worshiping us.”

10:68And they said, “God has taken a son.” Be He glorified. He is the Self-Sufficient. His is everything in the heavens and everything on earth. Do you have any proof for this? Or are you saying about God what you do not know?
