an atheists perspective is for his own thoughts and actions, and a believers perspective for a believers thoughts and actions. the greed for heaven is purely a believer's drive who is fully convinced of an afterlife. hence, "hedonism" is fully justified as a qualification to this pursuit as well.
i am familiar with the concept of hedonism being the base of virtue. in fact, i have even heard strange things from god-men that a good deed is a sin if it is not done with the intention of pleasing the supreme being for a place in heaven.
go figure. morality?
Peace queer
It may be that others have already argued the position of Islam on this already but I have further clarification to make inshaAllah.
Firstly it is not considered wrong to be experiencing the emotional desire that hedonists experience so long as that desire is aligned to God and attributed as a blessing from God. Hedonism is a fuelling of the ego by carnal fun and enjoyment in the present. To offset this for a desire in the Hereafter fundamentally differs because of the 'faith' aspect in the Hereafter and to forsake the immediate desire for self-control and obedience to God cannot be called hedonism.
To fear God is the lowest level of faith so people who fear God and are obedient to Him are doing good.
To love God is the highest level of faith and this love creates a devotional obedience to Him again is doing good. Anything in between i.e. to desire heaven and hence obey God is also good and it is not strictly hedonism because we do not desire things in this world in place of things in the Hereafter.
A deed is only good if it undertaken to please God, i.e. selflessly.
