And indeed We created towers in the skies, and beautified it for the beholders. 16 And We have guarded it (near heaven) from every outcast Shaitan (devil). 17 But he who steals a hearing, so there follows him a visible flame. 18 And the earth -- We stretched it forth, and cast on it firm mountains, and We caused to grow therein of every thing justly weighed, 19 And We have made for you therein means of living and [for] those for whom you are not providers. 20 With Us is the source of everything and We do not send it down except in a known quantity. 21 We send the winds fertilizing, and We send down out of heaven water, from which you drink and you are not its treasurers. 22 And verily, it is We Who give life, and Who give death: it is We Who remain inheritors (after all else passes away). 23 And indeed We know those among you who came forward and indeed We know those among you who remained behind. 24 and, behold, it is thy Sustainer who will gather them all together [on Judgment Day]: verily, He is Wise, All-Knowing! 25

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.
