In the Name of Allah, the Most Gracious, the Most Merciful.
The Result of Loving the World and Heedlessness of the Hereafter
Allah says that all are preoccupied by love of the world, its delights and its adornments, and this distracts you from seeking the Hereafter and desiring it. This delays you until death comes to you and you visit the graves, thus becoming its inhabitants. In Sahih Al-Bukhari, it is recorded in the Book of Ar-Riqaq (Narrations that soften the Heart) from Anas bin Malik, who reported that Ubayy bin Ka`b said, "We used to think that this was a part of the Qur'an until the Ayah was revealed which says;
Verse [ 102:8] ثُمَّ لَتُسْأَلُنَّ يَوْمَئِذٍ عَنِ النَّعِيمِ (Then you will be asked about all the pleasures [ you enjoyed in the world ].) This means that, on the Day of Judgment, all of you will be questioned whether you had shown gratitude towards Allah's favors, or did you misuse them and were ungrateful to Allah? Some of these favors and bounties are explicitly mentioned elsewhere in the Qur'an:
(...Surely, the ear, the eye and the heart - each one of them shall be interrogated about.) [ 17:36]
These organs and their faculties comprehend millions of blessings of Allah, and man will be questioned as to how he used them every moment of his life.
Man wants to earn more and more so that he may accumulate more and more material assets. He remains immersed in that thought till the day he dies. After his death, man realises that what was worth accumulating was something else. But the realization after death will be of no avail. Any increase in worldly goods increases a man’s accountability. But man, in his foolishness, thinks that he is adding to his success.
