[Pooya/Ali Commentary 79:3] There are angels who traverse all frontiers of the universe to carry out divine commands. They never lag behind or leave anything undone while executing the will of Allah. Aqa Mahdi Puya says: The first 3 verses refer to the preparatory work before any divine will takes effect which sets in motion that which is willed. Verses 4 and 5 refer to the administration or operation of the consequences of the divine will. The forces working in the universe operate in harmony under the laws made by the creator. There is no reason to restrict its application or reference to any particular agency. Refer to the commentary of Saffat: 1 to 3; Dhariyat: 1 to 4 and Mursalat: 1 to 5.
