Surah Al-Anfal Ayah 53

That is so because Allah will never change a grace which He has bestowed on a people until they change what is in themselves. And verily, Allah is All-Hearer, All-Knower (53)Similar to the behavior of the people of Fir'awn, and those before them. They belied the Ayat of their Lord, so We destroyed them for their sins, and We drowned the people of Fir'awn for they were all wrongdoers (54)

Allah affirms His perfect justice and fairness in His decisions, for He decided that He will not change a bounty that He has granted someone, except on account of an evil that they committed. Allah said in another Ayah,

إِنَّ اللَّهَ لَا يُغَيِّرُ مَا بِقَوْمٍ حَتَّىٰ يُغَيِّرُوا مَا بِأَنفُسِهِمْ ۗ وَإِذَا أَرَادَ اللَّهُ بِقَوْمٍ سُوءًا فَلَا مَرَدَّ لَهُ ۚ وَمَا لَهُم مِّن دُونِهِ مِن وَالٍ

(Verily, Allah will not change the (good) condition of a people as long as they do not change their state (of goodness) themselves. But when Allah wills a people's punishment, there can be no turning it back, and they will find besides Him no protector.)[13:11]

Allah said next,

كَدَأْبِ آلِ فِرْعَوْنَ

(Similar to the behavior of the people of Fir'awn,) meaning, He punished Fir'awn and his kind, those who denied His Ayat. Allah destroyed them because of their sins, and took away the favors that He granted them, such as gardens, springs, plants, treasures and pleasant dwellings, as well as all of the delights that they enjoyed. Allah did not wrong them, but it is they who wronged themselves.
