And verily in the heaven we have set mansions of the stars, and We have beautified it for beholders. 16 And We guard it against every accursed Shaitan, 17 so that anyone who seeks to learn [the unknowable] by stealth is pursued by a flame clear to see. 18 And the earth-- We have spread it forth and made in it firm mountains and caused to grow in it of every suitable thing. 19 and there appointed for you is a livelihood, and for those you do not provide. 20 And there is not a thing but that with Us are its depositories, and We do not send it down except according to a known measure. 21 And We send the winds fertilizing (to fill heavily the clouds with water), then caused the water (rain) to descend from the sky, and We gave it to you to drink, and it is not you who are the owners of its stores [i.e. to give water to whom you like or to withhold it from whom you like]. 22 It is We who give life and We who give death, and We are the One who will abide. 23 We surely know those of you who go forward and those of you who lag behind. 24 And surely your Lord will gather them together; surely He is Wise, Knowing. 25

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.
