Starting with "Hamd", I found 11 verses in which it has been used. There may be more or less though. One thing they all seem to imply is God likes to be acknowledged and praised exclusively as he wants us to see him behind everything done in this world.  By praising him we are telling him that we see you and we praise you for your everyday managing the world and subsequently our affairs.   There are obviously other people or other apparent means that seem to be the driving forces of all events taking place in world, yet he urges us to come to belief that he is the one in disguise of all these earthly  interactions and causes. 

"Abd" is usually translated to worship.  In fact it means more like being a slave of some one else. So what is the difference; if you understand it as worship then comes with it a religion full of rituals that you will have to do in order to prove you worship him. You become more a slave of rituals than a slave of him.  You will have to make yourself used to regular habitual acts of worships to prove to God and to your self that you are worshiping God despite your inside that may be totally out of him and may be in possession of many but him.

In contrast if "Abd" ,as I found in 50 verses, is to be understood as being surrounded to God as a slave puts his life in hands of his master, seeks what pleases him or ,for the best part, lives and breathes only and merely for  him regardless of different situations or whatever actions being involved in, then it brings you another religion; the one of engagement to the love of God. In that what ever you do is only for him, it is only an act of your love toward him, it is an energizing light that comes out of you, enlightening yourself and everything around you.   This way, it does not matter what you do or how you do any ritual or your mundane , what matters most is if you do it for God or not.

Last word in this post is "Magzoob" which comes from "Gazab" meaning anger. We can probably see this word used in 10/11 verses in different forms mostly showing anger of God in their context. The question however is , in the last verse of "Al-faatiha", if there are people who are guided and there are people who are lost ( the 1st & 3rd group) then why God may become angry with the middle group.  Could this anger means he cares for some who have a potential to be guided and come back to him ?  Could his anger be a sign of his love for us although it may feel painful and seem harsh on us ? If some one really loves another, isn't ii usually the case when one side shows ignorance the other party becomes very sensetive and usually angry ,to say the least ?
