And indeed, We have put the big stars in the heaven and We beautified it for the beholders. 16 And We have preserved it from every accursed devil, 17 Save him who stealeth the hearing, and him there followeth a flame gleaming. 18 We stretched the earth and placed upon it firm stabilisers, and made all things grow upon it balanced evenly. 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 the stores thereof. And we send it not down save in appointed measure. 21 And We send the fecundating winds, then cause the rain to descend from the sky, therewith providing you with water (in abundance), though ye are not the guardians of its stores. 22 It is We who give life and cause things to die and We are the sole Heirs. 23 And indeed We know those among you who came forward and indeed We know those among you who remained behind. 24 And verily thy Lord! He will gather them, and verily He is Wise, 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.
