Bismillah

Allah ta’ala says in surah Zukhruf,

وَلَوْلَا أَن يَكُونَ النَّاسُ أُمَّةً وَاحِدَةً لَّجَعَلْنَا لِمَن يَكْفُرُ بِالرَّحْمَـٰنِ لِبُيُوتِهِمْ سُقُفًا مِّن فِضَّةٍ وَمَعَارِجَ عَلَيْهَا يَظْهَرُونَ
وَلِبُيُوتِهِمْ أَبْوَابًا وَسُرُرًا عَلَيْهَا يَتَّكِئُونَ
وَزُخْرُفًا ۚ وَإِن كُلُّ ذَ‌ٰلِكَ لَمَّا مَتَاعُ الْحَيَاةِ الدُّنْيَا ۚ وَالْآخِرَةُ عِندَ رَبِّكَ لِلْمُتَّقِينَ

And if it were not that the people would become one community [of disbelievers], We would have made for those who disbelieve in the Most Merciful - for their houses - ceilings and stairways of silver upon which to mount, And for their houses - doors and couches [of silver] upon which to recline, And gold ornament. But all that is not but the enjoyment of worldly life. And the Hereafter with your Lord is for the righteous. (43:33-35)

In other words, were it not for fear that a believer might disbelieve as a result of Our giving the disbeliever what has been mentioned, We would have given him such [luxuries], since the [affairs of this] world represent no danger to Us and he [the disbeliever] would then have no share in the Bliss of the Hereafter. Yet surely all that would be nothing but the [transient] enjoyment of the life of this world, enjoyed during it, but then perishes, and the Hereafter, Paradise, with your Lord is for the God-fearing.

-Imam Suyooti rahimahullah: Tafseer al-Jalalayn

Allah azza wa jal tells us in these ayat that the dunya has no value with Him, and that if it wasn’t for His subtle kindness and mercy on His slaves, He would surely have greatly expanded this dunya for the disbelievers by giving them stairways of silver that mount and He would have given them ornaments of different kinds and anything they desired - but He prevented this out of His Mercy for His slaves fearing for them that they would hasten to disbelief and increase in disobedience because of the love of this world.
So this is a proof that He prevents certain matters of the dunya in a general sense and a special sense for the reformation of the believers. [And this is also a proof that] the dunya does not even amount to the weight of a mosquito wing with Allah. What is mentioned in this ayah is only the transient and deficient enjoyment of this world, but the hereafter with Allah is better from those who are conscious and have taqwa of their Lord by following what He has ordered and abstaining from what He has forbidden, because its pleasures are complete and perfect in every way. In Jannah there is everything that the soul desires and delight for the eyes, and they will abide therein eternally……Then how great is the difference between these two homes!
