2846 Land and sea have been made subject to man by Allah's command, so that man can develop his life freely on earth. 2847 Sama '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 word 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.
