Allah has promised to believers, men and women, gardens under which rivers flow, to dwell therein, and beautiful mansions in gardens of everlasting bliss. But the greatest bliss is the good pleasure of Allah: that is the supreme felicity. (Surat at-Tawba: 72)
It is evident that paradise is a place containing all the joys man can experience through his five senses. However, the superior quality of paradise is the good pleasure of Allah. For believers, attaining the good pleasure of Allah becomes a major source of peace and joy in the hereafter. Furthermore, seeing the favours of Allah and being grateful to Allah for His benevolence makes them happy. In the Qur'an, the believers in paradise are described as follows:
...Allah is well pleased with them and they with Allah. That is the great salvation, (the fulfilment of all desires). (Surat al-Ma'ida: 119)
What makes the favours of paradise so precious is the good pleasure of Allah. The same types of favours may also exist in this world, yet if the good pleasure of Allah is not involved, believers do not enjoy these favours. This is a very important issue on which one needs to ponder. What actually makes a favour precious is something beyond the savour and pleasure it gives. What really matters, is the fact that Allah has bestowed that favour.
A believer who has the benefit of such a favour and is grateful to his Creator derives his main pleasure from knowing that it is the benevolence of Allah. The satisfaction can be found only from the fact that Allah protects him, loves him and that his Creator shows His Mercy to him. Therefore, one's heart only takes pleasure from paradise. He is created to be a servant of Allah and therefore he takes only pleasure from His benevolence.
In brief, paradise is a gift of Allah to His true servants and that is why it is important to them. Since "they are (but) slaves raised to honour," (Surat al-Anbiya: 26) they attain eternal happiness and joy. The words of the believers in paradise are "Blessed be the name of your Lord, full of Majesty, Bounty and Honour." (Surat ar-Rahman: 78)
