THE WAY:JESUS
Yes Jesus(pbuh) did preach the way, the way that is straight and not crooked, for he preached believe in the one God who hath created the heaven and the earth.
THE TRUTH:HOLY GHOST
The Holy Ghost according to Islam, is the angel Gabriel. And indeed did Gabriel bring the Truth from God, "There is no God, but God"
THE LIFE:FATHER
Indeed God hath power over life and death, for only He can control those forces for He has power over all things. God is in a way a Father to all of mankind who believes in Him and worships Him alone. I am His humble servant.
You see God is in connection with these three things, but not in the way that Christanity connects them, with due respect of course. All things come from God, the way, the truth, and the life. But "Say not God has begotten a son nor is He begotten... Say not God is third or part in a Trinity, for There is no God but God."
May peace be upon you
