We have set in heaven constellations and decked them out fair to the beholders, 16 And (moreover) We have guarded them from every cursed devil: 17 But he who steals a hearing, so there follows him a visible flame. 18 We have spread out the earth, and set upon it firm mountains and caused everything to grow in due proportion. 19 and provided thereon means of livelihood for you [O men] as well as for all [living beings] whose sustenance does not depend on you. 20 There is not a thing but its storehouses are with Us. But We only send down each thing in an appropriate measure: 21 And We send the winds fertilizing, then We send down water from the heaven and We give it to you to drink, and thereof ye could not be the treasurers. 22 for, behold, it is We - We alone - who grant life and deal death, and it is We alone who shall remain after all else will have passed away! 23 Surely We know those of you who have passed before and those who will come later. 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.
