And indeed We created towers in the skies, and beautified it for the beholders. 16 And We guard it against every accursed Shaitan, 17 Save him who stealeth the hearing, and him there followeth a flame gleaming. 18 And the earth - We have spread it out wide, and placed on it mountains firm, and caused [life] of every kind to grow on it in a balanced manner, 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 a thing but with Us are the stores thereof. And we send it not down save in appointed measure. 21 We send impregnating winds and send down water from the sky for you to drink and you have no (control over its) storage. 22 It is indeed We Who grant life and cause death and it is We who shall be the sole Inheritors of all. 23 We know those of you who press forward, and We know the laggards, 24 And verily, your Lord will gather them together. Truly, 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.
