We have placed the signs of the Zodiac in the sky, and decked it out for those who can see; 16 and We have guarded it from every accursed devil: 17 excepting such as listens by stealth -- and he is pursued by a manifest flame. 18 And the earth! We have stretched it out and have cast thereon mountains firm, and We have caused to spring up thereon everything weighed. 19 And created livelihoods for you in it, and created those for whom you do not provide the sustenance. 20 With Us is the source of everything and We do not send it down except in a known quantity. 21 And We let loose the winds to fertilize [plants] and We send down water from the skies and let you drink thereof: and it is not you who dispose of its source 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 who lived before you and those who will come after you. 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.
