﴿ وَأَصْبَحَ ٱلَّذِينَ تَمَنَّوْا۟ مَكَانَهُۥ بِٱلْأَمْسِ يَقُولُونَ وَيْكَأَنَّ ٱللَّهَ يَبْسُطُ ٱلرِّزْقَ لِمَن يَشَآءُ مِنْ عِبَادِهِۦ وَيَقْدِرُ ۖ لَوْلَآ أَن مَّنَّ ٱللَّهُ عَلَيْنَا لَخَسَفَ بِنَا ۖ وَيْكَأَنَّهُۥ لَا يُفْلِحُ ٱلْكَٰفِرُونَ ﴾

“And on the morrow, those who but yesterday had longed to be in his place exclaimed: “Alas [for our not having been aware] that it is indeed God [alone] who grants abundant sustenance, or gives it in scant measure, unto whichever He wills of His crea­tures! Had not God been gracious to us, He might have caused [the earth] to swallow us, too! Alas [for our having forgotten] that those who deny the truth can never attain to a happy state!””

According to the Bible, Moses cursed Korah for his evil deeds, and God caused him, his companions and his treasure to be swallowed up by the earth. This was visibly demonstrated by God as an example to clarify what the final result would be of leaving off the worship of God and adopting the worship of wealth. The amenities of the world are in fact given as a trial of human beings. These are provided to man, by the will of God in greater or lesser quantities. It is the duty of man to be patient if he receives fewer amenities and to be grateful if he receives more. This is the only way to the salvation and success of man.
