Surah 22. Al-Hajj, Ayah 65

Lit., "the sky" - used here as a metonym for the stars and planets, which are held on their courses by the God-willed laws of cosmic movement (Maraghi XVII, 137).

I.e., "has enabled you to benefit from all. . .", etc. (cf. surah {14}, note [46]).

I.e., at the Last Hour, which - as the Qur'an so often states - will manifest itself in universal cosmic catastrophe.

 For your service.

Land and sea have been made subject to man by Allah's command, so that man can develop his life freely on earth.

Samaa means (1) something high, (2) a roof, a ceiling, (3) the sky, the canopy of heaven. (4) cloud or rain. I understand the last meaning here, though most authorities seem to render it by some such words as "sky". If we understand rain here, we have a complete picture of the three elements in which man lives-land, air and sea. Rain is also appropriate for mention with Allah's kindness and mercy. He regulates the rain for man's benefit.
