And a sign for them is the dead land, that We quickened and brought forth from it grain, whereof they eat; 33 And We make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 so that they may eat of the fruit thereof, though it was not their hands that made it. Will they not, then, be grateful? 35 Hallowed be He who hath created all the pairs of that which the earth groweth, and of themselves and of that which they know not! 36 They have a sign in the night: We withdraw from it the [light of] day -- and they are left in darkness. 37 And the sun runs on to a term appointed for it; that is the ordinance of the Mighty, the Knowing. 38 And the moon, We have measured for it mansions (to traverse) till it returns like the old dried curved date stalk. 39 It is not permitted to the sun that it should overtake the moon, nor can the night outstrip the day: each in an orbit, they float. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 And We have created for them of the like thereunto, so on them they ride. 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 43 Unless it be a mercy from Us, and as an enjoyment for a while. 44 And when it is said unto them: fear that which is before you and that which is behind you, that haply ye may find mercy, they withdraw. 45 And there comes not to them a communication of the communications of their Lord but they turn aside from it. 46 And when it is said to them, "Spend from that which Allah has provided for you," those who disbelieve say to those who believe, "Should we feed one whom, if Allah had willed, He would have fed? You are not but in clear error." 47 They also say, 'When shall this promise come to pass, if you speak truly?' 48 They wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 Then they cannot make bequest, nor can they return to their own folk. 50

Notes and Instructions
كيف تعمل منظومة تمارين الحفظ؟ عند أدنى مستوى 0، تكون كل الكلمات ظاهرة. بينما يُخفي أعلى مستوى 9 كل الكلمات. فكيف تعمل المستويات المتوسطة، مثل 3، على سبيل المثال؟ قد تعتقد بأن المنظومة تخفي 3 من كل تسع كلمات بدقة. ليس تماما! في المستوى 3، لكل كلمة فرصة اختفاء بنسبة 3 من 9، و6 من 9 لتكون ظاهرة. بمعنى آخر، من الممكن، ولكن باحتمال شبة معدوم، أن تكون جميع كلمات المستوى 3 مخفية، أو أن تكون جميعها ظاهرة! وكذلك أيضًا، ففي المستويات المتوسطة، وبما يتناسب مع مستوى الصعوبة، يمكن أن تكون المخابئ غير كاملة أو شفافة جزئيًا بحيث تظهر الكلمات جزئيًا تحتها.
How does the memorization exercise algorithm work? At the lowest level 0, all words are visible. While the highest level 9 hides all words. What about at mid-level, like 3, for example? You might think that the algorithm hides precisely 3 out of every nine words. Not quite! At level 3, each word has a 3 out of 9 chance to hide, and 6 out of 9 to be visible. In other words, it is possible, but highly unlikely, for all words at level 3 to be hidden, or, that all of them to be visible! Also, at mid-levels, and in proportion to the difficulty level, hideouts can be partially incomplete or transparent so that words may be partially visible underneath.
