How Qarun and His Dwelling Place were swallowed up by the Earth

After telling us about Qarun's conceit and pride in his adornments, and how he was arrogant towards his people and transgressed against them, Allah then tells us how he and his dwelling place were swallowed up by the earth. This was also reported in the Sahih by Al-Bukhari from Salim, who said that his father told him that the Messenger of Allah ﷺ said:

«بَيْنَمَا رَجُلٌ يَجُرُّ إِزَارَهُ إِذْ خُسِفَ بِهِ، فَهُوَ يَتَجَلْجَلُ فِي الْأَرْضِ إِلَى يَوْمِ الْقِيَامَة»

وَقَالَ الَّذِينَ أُوتُوا الْعِلْمَ وَيْلَكُمْ (And said those who were given knowledge - 28:80). This verse has compared the knowledgeable persons with الَّذِينَ يُرِ‌يدُونَ الْحَيَاةَ الدُّنْيَا (Those who are desirous of the worldly life - 28:79), which clearly indicates that it is not the trait of knowledgeable persons to aspire for the acquisition of wealth and to make it the object of life. They always keep their eyes toward the lasting benefits of the Hereafter. As for the mundane wealth, they take it only to fulfill their day-to-day needs, and stay content with that.
