And not alike are the two seas [i.e., bodies of water]. One is fresh and sweet, palatable for drinking, and one is salty and bitter. And from each you eat tender meat and extract ornaments which you wear, and you see the ships plowing through [them] that you might seek of His bounty; and perhaps you will be grateful.
He causes the night to enter the day, and He causes the day to enter the night and has subjected the sun and the moon - each running [its course] for a specified term. That is Allāh, your Lord; to Him belongs sovereignty. And those whom you invoke other than Him do not possess [as much as] the membrane of a date seed.
And no bearer of burdens will bear the burden of another. And if a heavily laden soul calls [another] to [carry some of] its load, nothing of it will be carried, even if he should be a close relative. You can only warn those who fear their Lord unseen and have established prayer. And whoever purifies himself only purifies himself for [the benefit of] his soul. And to Allāh is the [final] destination.
