Peace after the first Tashahhud by mistake

Question
What is the ruling for someone who prayed Dhuhr and gave Salam after the first Tashahhud, and remembered at that very moment? Should they repeat the prayer, or should they continue? And should they perform Sujud al-Sahw?
Answer
I say, and with God's help: he should complete his prayer and perform the prostration for forgetfulness, and God knows best.
