The test and trial of believers in this worldly life

قَالَ أَرَءَيْتَكَ هَـٰذَا ٱلَّذِى كَرَّمْتَ عَلَىَّ لَئِنْ أَخَّرْتَنِ إِلَىٰ يَوْمِ ٱلْقِيَـٰمَةِ لَأَحْتَنِكَنَّ ذُرِّيَّتَهُۥٓ إِلَّا قَلِيلًا

[Iblees] said, "Do You see this one whom You have honored above me? If You delay me [i.e., my death] until the Day of Resurrection, I will surely destroy his descendants, except for a few."
