It is He who sends down rain from the sky; from it is drink and from it is foliage in which you pasture [animals]. 10 And with it He grows for you corn, and the olive and the date-palm and the grape, and all kinds of fruits. Surely, in that is a sign for a people who reflect. 11 And He hath constrained the night and the day and the sun and the moon to be of service unto you, and the stars are made subservient by His command. Lo! herein indeed are portents for people who have sense. 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 And He hath cast into the earth firm hills that it quake not with you, and streams and roads that ye may find a way. 15 And waymarks; and by the star they are guided. 16 Is then the One Who creates like the one who does not create? Will you not, then, take heed? 17 If ye would count up the favours of Allah, never would ye be able to number them: for Allah is Oft-Forgiving, Most Merciful. 18 God knows all that you conceal and all that you reveal. 19 Those unto whom they cry beside Allah created naught, but 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.
