Alpha, we must be careful in discussing "the Fathers superiority over the Son". Although scripture clearly indicates this, we must take into account the ENTIRE scripture and nature of God.
1. Jesus willingly submits to the Father, and voluntarily takes on human form. Scripiture would also indicate that Christ resides at the right hand of the Father in glorified human form.
2. Willing submission in NO WAY implies inferiority in the nature of The Father vs the Son. Just as a wife is equal to the husband, she willingly submits (if she is a good Chrisian wife) Muslims have a real hard time with this concept since submission relates to someone or thing that is lessor to the one they submit too.
3. In the Godhead we see Christ as the Fathers equal, but willingly takes on an inferior role, to do the Fathers will. It is important to distiguish a willing and purposeful shedding of authority and power vs. lessor or inferior in nature. Jesus in NOT inferior in any way to the Father, except by His choice of submission. All the passages that our Muslim friend quoted must be understood in the nature and context of true scripture, which of course, the Muslims are not open too.
