John the Baptist (Yahya al-Islam) was calling people to repentance in the wilderness. They would confess their sins and be 'dunked' into the water as act of repentance.
"In those days John the Baptist came, preaching in the wilderness of Judea and saying, “Repent, for the kingdom of heaven has come near.” - Matthew 3:1-2 (NIV).
"People went out to him from Jerusalem and all Judea and the whole region of the Jordan. Confessing their sins, they were baptized by him in the Jordan River." - Matthew 3:5-6 (NIV).
"Then Jesus came from Galilee to the Jordan to be baptized by John." - Matthew 3:13 (NIV).
"Jesus replied, “Let it be so now; it is proper for us to do this to fulfill all righteousness.” Then John consented." - Matthew 3:15 (NIV).

According to the New Testament, Jesus came to John to be baptized. The only kind of baptism which John offered was for the baptism for the repentance of....sins!
Note: Nowhere in the Gospel According to the Unknown Author of Matthew does any scribe state that Jesus was sinless.
