We have indeed set constellations in the heavens and have beautified them for the beholders, 16 and have protected them against every accursed satan 17 except for those who stealthily try to listen to the heavens, but who are chased away by a bright flame. 18 And the earth-- We have spread it forth and made in it firm mountains and caused to grow in it of every suitable thing. 19 And We have provided therein means of living, for you and for those whom you provide not [moving (living) creatures, cattle, beasts, and other animals]. 20 Naught is there, but its treasuries are with Us, and We send it not down but in a known measure. 21 And We sent the winds that relieve the clouds’ burden, therefore caused water to descend from the sky, then give it to you to drink; and you are not at all its treasurers. 22 And verily, it is We Who give life, and Who give death: it is We Who remain inheritors (after all else passes away). 23 And well do We know [the hearts and deeds of all human beings - both] those who lived before you and those who will come after you; 24 and it is your Lord who will gather them. 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.
