John 9:11-15
John 9:11 (KJB)
He answered and said, A man that is called Jesus made clay, and anointed mine eyes, and said unto me, Go to the pool of Siloam, and wash: and I went and washed, and I received sight.
The man gives a full answer as to how the events had transpired. Jesus made the clay, applied it to my eyes, and then commanded me to go to the pool of Siloam and wash, then as I washed, I was able to see. He left no details out so this way it proved who he was plus he identified Jesus as his healer. He did not know at this point who Jesus was, all he knew was that he was once blind but now he saw.
John 9:12 (KJB)
Then said they unto him, Where is he? He said, I know not.
Then they asked him if they knew where He had gone? Of course, since the man was blind when he first met Jesus, he did not know where Jesus went or even what He looked like, so he would be unable to point Jesus out.
John 9:13 (KJB)
They brought to the Pharisees him that aforetime was blind.
It was customary to show oneself to the priests if a notable miracle or healing has happened. This way you would be declared clean and would be allowed to join or rejoin the Temple services. They probably also brought him to the Pharisees for the purpose of getting some theological opinions on the matter. They wanted to know if they knew who walked among them with such power to heal even blind eyes from birth.
John 9:14 (KJB)
And it was the sabbath day when Jesus made the clay, and opened his eyes.
The Pharisees were not concerned about the fact that this man was healed from blindness but all they focused in on was the fact that it was done on the Sabbath. Jesus also healed the man at the pool of Bethesda on the Sabbath in John 5. Jesus had faced the same mindset. They were not concerned that the man was healed after 38 years of infirmity, their focus was on the fact that Jesus healed him on the Sabbath.
John 9:15 (KJB)
Then again the Pharisees also asked him how he had received his sight. He said unto them, He put clay upon mine eyes, and I washed, and do see.
Now he is questioned by the Pharisees as to how he regained his sight. The man then goes into the procedure once again but shortens the account. He probably sensed there was an air of opposition and contention concerning Jesus who did the miracle on the Sabbath. Here the Pharisees could have claimed that both had violated the Sabbath. Jesus made the clay which would have been a work and the man went and washed which would have been a work. This is religion at its best when it opposes the true work of God.
