What the Prophet (peace be upon him) promised to humanity:
The believers will have all that the heart desires in Paradise
In Islam teaches that Paradise, in contrast to that which is taught my secularised religions and ideologies, is not something merely symbolic, rather, it is a tangible place. One’s entrance into Paradise entails enjoying physical and emotional pleasures which that one cannot even begin to comprehend.
There are many verses from the Quran and authentically narrated sayings from the Prophet (peace be upon him) which say that the residents of Paradise will have whatever their hearts desire and more:
“Trays of gold and cups will be passed round them; (there will be) therein all that inner-selves could desire, and all that eyes could delight in and you will abide therein forever” [al-Zukhruf 43:71]
Al-Sa’di said in his commentary on this verse:
“…all that inner-selves could desire…” – this phrase is comprehensive and includes every kind of blessing, joy, delight and pleasure, in the most perfect and best sense.
And Allah says (interpretation of the meaning):
“‘Adn (Eden) Paradise (Gardens of Eternity) which they will enter, under which rivers flow, they will have therein all that they wish. Thus Allah rewards the Muttaqoon (the pious)” [al-Nahl 16:31]
The Prophet (peace be upon) said: “Allah says: ‘I have prepared for My righteous slaves that which no eye has seen, no ear has heard and it has never crossed the mind of man.’ Recite if you wish: ‘No person knows what is kept hidden for them of joy as a reward for what they used to do’ [al-Sajdah 32:17 – interpretation of the meaning].” 
It was narrated from Sulaymaan ibn Buraydah from his father that a man asked the Prophet (peace be upon), “O Messenger of Allah, are there horses in Paradise?” He said, “If Allah admits you to Paradise, any time you wish to be carried on a horse of red rubies that will fly with you wherever you want in Paradise, you will do that.” Another man asked him, “O Messenger of Allah, will there be camels in Paradise?” and he did not say to him something like he said to his companion. He said, “If Allah admits you to Paradise, you will have there whatever your heart desires.” 
A person should be certain of the absolute perfection of Paradise and of its people’s happiness.
