We have indeed set constellations in the heavens and have beautified them for the beholders, 16 And We have protected it from every devil expelled [from the mercy of Allah] 17 Save him who stealeth the hearing, and them doth a clear flame pursue. 18 And We spread out the earth, and placed mountains as anchors in it, and in it grew all things by a proper measure. 19 And We have made for you therein means of living and [for] those for whom you are not providers. 20 And there is not a thing but with Us are its treasuries, and We do not send it down except in a known measure. 21 We send rain-impregnated winds, and water from the sky which you drink, but you are not the keepers of its store. 22 And indeed, it is We who give life and cause death, and We are the Inheritor. 23 Surely We know those of you who have passed before and those who will come later. 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.
