The Prophet Muhammad (peace be upon him) told us that the lowest in rank among the dwellers of Paradise will have ten times the like of this world, and he or she will have whatever he or she desires and ten times like it. Also, the Prophet Muhammad said: "A space in Paradise equivalent to the size of a foot would be better than the world and what is in it." He also said: "In Paradise there are things which no eye has seen, no ear has heard, and no human mind has thought of." He also said: "The most miserable man in the world of those meant for Paradise will be dipped once in Paradise. Then he will be asked, “Son of Adam, did you ever face any misery? Did you ever experience any hardship?” So he will say, “No, by God, O Lord! I never faced any misery, and I never experienced any hardship.”"

Paradise: There is Nothing Like It
The delights of Paradise surpass the imagination and defy description. They are like nothing known to the people of this world; no matter how advanced we may become, what we achieve is as nothing in comparison with the joys of the Hereafter. As is mentioned in several reports, there is nothing like Paradise: “It is sparkling light, aromatic plants, a lofty palace, a flowing river, ripe fruit, a beautiful wife and abundant clothing, in an eternal abode of radiant joy, in beautiful soundly-constructed high houses”. (Ibn Maajah, Ibn Hibbaan)
The Sahabah asked the Prophet about the buildings of Paradise and he replied with a wonderful description: “Bricks of gold and silver, and mortar of fragrant musk, pebbles of pearl and sapphire, and soil of saffron. Whoever enters it is filled with joy and will never feel miserable; he will live there forever and never die; their clothes will never wear out and their youth will never fade.” (Ahmad, at-Tirmidhi, ad-Daarimee)

The Prophet said that Allah said: “I have prepared for My slaves what no eye has seen, no ear has heard and no human heart can imagine.” Recite if you wish:

In another report:
“Never mind what Allah has told you; what He has not told you is even greater.” (Saheeh Muslim)
