We have indeed set constellations in the heavens and have beautified them for the beholders, 16 And We have guarded it from every outcast devil, 17 Except one who steals a hearing and is pursued by a clear burning flame. 18 We have spread out the earth and set upon it firm mountains. Everything We have caused to grow therein is justly weighed; 19 And We have appointed thereon for you livelihoods and also for those of whom ye are not the providers. 20 And there is not of aught but with Us are the treasures thereof, and We send it not down save in a measure known 21 And We have sent the fertilizing winds and sent down water from the sky and given you drink from it. And you are not its retainers. 22 It is We who give life and cause things to die and We are the sole Heirs. 23 And We have already known the preceding [generations] among you, and We have already known the later [ones to come]. 24 Indeed your Lord will gather them all together. Surely He is All-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.
