Mentioning the Story of Musa and that it is a Lesson for Those Who fear Allah

Allah informs His Messenger Muhammad ﷺ about His Messenger Musa. He mentions that he sent Musa to Fir`awn and He aided him with miracles. Yet, even after this, Fir`awn continued in his disbelief and transgression until Allah seized him with a mighty and powerful punishment. Thus is the punishment of whoever opposes you (Muhammad ﷺ) and rejects that which you have been sent with. This is why Allah says at the end of the story,

إِنَّ فِى ذَلِكَ لَعِبْرَةً لِّمَن يَخْشَى

The fifth quality of the angels:

فَالْمُدَبِّرَ‌اتِ أَمْرً‌ا (then manage [ to do ] everything [ they are ordered to do,]...79:5). In other words, the last task of these angels of death will be as follows: Those who are commanded to reward and comfort the deserving souls, will gather means of reward and comfort for them; and those who are commanded to punish and cause pain to [ the evil souls ] will organize means for that.
