It is He Who sent down water from the sky you drink from it, and from it are trees you use as pasture. 10 Therewith He causeth crops to grow for you, and the olive and the date-palm and grapes and all kinds of fruit. Lo! herein is indeed a portent for people who reflect. 11 God has made the day and the night, the sun and the moon, and all the stars subservient to you by His command. In this there is evidence of the truth for people of understanding. 12 And what He has multiplied for you in the earth is of various hues; surely, in that there is a sign for a nation who remember. 13 And He it is who has made the sea subservient [to His laws,] so that you might eat fresh meat from it, and take from it gems which you may wear. And on that [very sea] one sees ships ploughing through the waves, so that you might [be able to] go forth in quest of some of His bounty, and thus have cause to be grateful [to Him]. 14 He has set up on the earth firm mountains, lest it shake under you, and rivers and tracks, so that you may find your way, 15 And landmarks. And by the stars they are [also] guided. 16 Is then the One Who creates like the one who does not create? Will you not, then, take heed? 17 If you count the favors of Allah, you could not number them. Indeed, Allah is Forgiving and the Most Merciful. 18 And Allah knows what you conceal and what you reveal. 19 Whatever (idols) they worship besides God can create nothing for they are themselves created. 20 (They are things) dead, lifeless: nor do they know when they will be raised up. 21

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.
