Who is the most successful religious leader in the world?

Moses has been debated as the most successful religious leader.Some also take the name of Jesus but objectively when you look at it...No one comes near to the founder of Islam--Muhammad !!

He changed the whole world forever.He himself supervised the writing of Qur'an.He gave a new law code (which is followed by ~25% of total population).At the time of death,Muhammad had 140,000 followers while Jesus had mere 9 disciples...
