It is We Who have set out the zodiacal signs in the heavens, and made them fair-seeming to (all) beholders; 16 And We have protected it from every devil expelled [from the mercy of Allah] 17 Save him who stealeth the hearing, and them doth a clear flame pursue. 18 We have spread out the earth, fixed mountains thereupon and caused everything to grow to its proper weight 19 and there appointed for you livelihood, and for those you provide not for. 20 And there is not a thing but its (sources and) treasures (inexhaustible) are with Us; but We only send down thereof in due and ascertainable measures. 21 And We loose the winds fertilising, and We send down out of heaven water, then We give it to you to drink, and you are not its treasurers. 22 And indeed it is We Who give life and it is We Who cause death, and We are the Inheritors. 23 And assuredly We know those of you who have gone before and those who will come hereafter. 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.
