Quran has made numerous promises about ... 72 virgin girls that their skin are so transparent and clean that they are visible even after 20 layer of clothes..
Can you mention the verses about 72 virgins and the silly statement about 20 layers of clothes? And if it is meant to be seen, then why the clothes? lol. I know no such verses exist in Quran.
As for the question, Quran adresses all people. People of zuhd who no worldly desires can possess are the adressees. Just like lustful people are the adressees. And, the point in describing heaven for the both, is to remind them the kingdom of God is what our true aim should be. Being in His kingdom and graced with His pleasure.
But, when people think of the worldly things and pleasures, Quran and especially hadiths remind them, "they are transient in this world. Yet if it is what you aim though, ask a permanent one. Because you'll not reach them here in this world and if you reach, you'll lose them in this world. So, ask the permanent, not the transient." But, it doesn't mean the real Paradise is just limited to this. Real Paradise is to be in nearness (not as in physical) to the Lord, being with Him. But, we don't usually see the real Paradise which is described in the Holy Quran. Please refer to the prayer of Asiya, (whom the Quran refers to an example to the believing men and women), when she wants to be saved from the Pharaoh and his people. What she asks is Paradise. But when she describes Paradise, she makes no mention of these things. Instead she says she wants to be with God. True, there is only a "house" mentioned in her prayer. But, we shouldn't think of it as a worldly thing. Because "Oh God, grant me WITH YOU a house in Paradise" means, "I want to be in seclusionw WITH YOU only. Because, a house with no other than God is in (please note that this is metaphorical not literal), means that, you want no company, friends, spouses, children or any pleasures. Only God. You only wish to be with Him. Please see:
Lastly, Imam Jafar Sadiq says; "Worship is of three kinds: some people worship Allah, because they fear Him – so it is the worship of slaves; and a group worships Allah, Blessed and High is He, to seek reward – so it is the worship of hirelings-merchants; and a group worships Allah, Mighty and Great is He, because of (His) love – and this is the worship of the free, and it is the most excellent worship."
I hope it helps. ma salam
