Surah 10. Yunus, Ayah 22

Lit., "until, when you are in the ships...", etc. As has been pointed out by Zamakhshari, the particle "until" (hatta) which precedes this clause refers to the sudden rise of the storm described in the sequence, and not to the "going to sea in ships". It is to be noted that at this point the discourse changes abruptly from the direct address "you" to the third person plural ("they"): a construction which is evidently meant to bring out the allegorical character of the subsequent narrative and to turn it into a lesson of general validity.

All the great inventions and discoveries on which man prides himself are the fruit of that genius and talent which Allah has freely given of His grace. But the spirit of man remains petty, as is illustrated by the parable from the sea. How the heart of man rejoices when the ship goes smoothly with favourable winds! How in adversity it turns, in terror and helplessness, to Allah, and makes vows for deliverance! and how those vows are disregarded as soon as the danger is past! Cf. vi. 63.
