TDR throws some raw gems here & there in to the forum., 
  I don't understand this. The entire purpose of the religion is attaining salvation and entering heaven by performing the right deeds and avoiding sinful deeds. The entire religion is based upon the belief that Muhammad's claims to being a prophet of god were true. 
If you accept that Muhammad's claims were false then there is no purpose in prayer,, no purpose in hajj, no purpose in fasting, no purpose in avoiding "sinful" deeds if there is nothing immoral about them. 
Not to mention the concept of tawhid and the shahada itself become meaningless. 
Let me collect that and   polish a bit  to write two statements out of that one.  
One for Islam and other one for all faiths/faith heads . 

  ... The entire purpose of  Islam as religion  is attaining salvation and entering heaven by performing the right deeds and avoiding sinful deeds. This whole faith is based upon the belief that Muhammad's claim  being the perfect last prophet of god and Quran is perfect  last word of god  are  true. 
If you accept that Muhammad's claims were false then there is no purpose in Islamic prayer,, no purpose in hajj, no purpose in fasting and no purpose in avoiding "sinful" deeds if there is nothing immoral about them. On top of all that the basic concept of Islam "tawhid and the shahada"  become just meaningless words at best and self deception and deceiving other at worst.........TheDarkRebel 
That is for Islam and this is for All Religions/All Faiths and 
to All Faith heads...lol..
 The entire purpose   a religion or a faith in this super god supreme deity is  based upon the design to focus the attention and energy of human beings on a single, unknown,  unchanging, uncompromising,  invisible supreme being described ancient/medieval cave dwellers written in some silly books as god/human/prophet chi chats. This  super god supreme deity allegedly created an inferior human race just for some extra companionship and love for himself and then supposedly foisted a set of oppressive and in some cases arbitrary rules on them, which if broken would be met with unimaginable punishment in this life and after this life.
Any faith or any religion which does  not agree with the above statement should not be considered as religion  but a religious hypothesis that is open to debate, to question and  to modify as we go along in life..   
And my good wishes to you dear TDR
