Amatul Rahmân Omer:
And We made such winds serve Solomon the blowing of which in the forenoon (and thus help sailing of his ships) was equal to (a voyage of) a month (by the other ships); similarly its blowing in the afternoon was (also) equal to (a voyage of) a month (by them). And We made a spring of molten copper to flow for him. Also (given into his service were) some of the jinns (- wild and rebellious mountain tribes known as Amalaqites), who worked under him as trained craftsmen) by the command of his Lord. And (We also told them) whoever of them deviated from and disobeyed Our command (- that they should obey Solomon) We shall make him suffer the agony of burning.
