﴿ وَٱضْرِبْ لَهُم مَّثَلَ ٱلْحَيَوٰةِ ٱلدُّنْيَا كَمَآءٍ أَنزَلْنَٰهُ مِنَ ٱلسَّمَآءِ فَٱخْتَلَطَ بِهِۦ نَبَاتُ ٱلْأَرْضِ فَأَصْبَحَ هَشِيمًۭا تَذْرُوهُ ٱلرِّيَٰحُ ۗ وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ مُّقْتَدِرًا ﴾

“AND PROPOUND unto them the parable of the life of this world: [it is] like the water which We send down from the skies, and which is absorbed by the plants of the earth: but [in time] they turn into dry. stubble which the winds blow freely about. And it is God [alone] who determines all things.”

The word: حُسبانا - (husbana) in verse 40 has been explained by Qatadah as 'punishment' in an absolute sense, by Sayyidna Ibn ` Abbas ؓ as 'fire' and by some as 'stoning.' As for what appears after that in the Qur'an: أُحِيطَ بِثَمَرِ‌هِ (And its produce was struck by destruction from all sides - 42), it obviously means that some major calamity hit his gardens, wealth and things of luxury reducing everything to ruins. The Qur'an does not mention any particular calamity explicitly. It appears that, some fire came down from the skies and burnt the whole thing - as it appears in the Tafsir of 'husban' by Sayyidna Ibn 'Abbas ؓ who has explained it as 'fire.' And Allah knows best.
