And a sign for them is the dead earth. We have brought it to life and brought forth from it grain, and from it they eat. 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 That they may eat of His fruit. And their hands have not produced it, so will they not be grateful? 35 Glory to Allah, Who created in pairs all things that the earth produces, as well as their own (human) kind and (other) things of which they have no knowledge. 36 And a sign unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 The sun, too, follows its determined course laid down for it by the Almighty, the All Knowing. 38 how We ordained the moon to pass through certain phases until it seems eventually to be like a bent twig; 39 The sun shall not outstrip the moon, nor shall the night outstrip the day. Each is floating in an orbit. 40 And a sign for them is that We lodged them in a laden ship, while they were in their forefathers backs. 41 And We created for them from the likes of it that which they ride. 42 If it were Our will, We could drown them: then there would be no helper [to hear their cry], nor could they be saved. 43 Unless by mercy from Us and as comfort 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 Indeed, not one of your Lord's signs comes to them without their turning away from it, 46 And when it is said unto them: Spend of that wherewith Allah hath provided you, those who disbelieve say unto those who believe: Shall we feed those whom Allah, if He willed, would feed? Ye are in naught else than error manifest. 47 Further, they say, "When will this promise (come to pass), if what ye say is true?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 Therefore neither able to make a will, nor returning to their homes. 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.
