And the distributors of command,
Ali said, it refers to "The angels."
Some scholars said that Al-Jariyat Yusra refers to the stars that float in their orbits with ease. This would mean that the things mentioned were ascendant in their order, beginning with the lower, then mentioning the higher one after that, etc. The winds bring the clouds, the stars are above them and the angels who distribute by Allah's order are above that, and they descend with Allah's legislative orders and the decrees He determines.
These Ayat contain a vow from Allah that Resurrection shall come to pass.
Allah's statement,
إِنَّمَا تُوعَدُونَ لَصَادِقٌ
