And certainly We have made strongholds in the heaven and We have made it fair seeming to the beholders. 16 and We have made them secure against every satanic force accursed 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. Everything We have caused to grow therein is justly weighed; 19 We have provided therein a means of livelihood for you and for all those creatures for whom you do not provide. 20 For, no single thing exists that does not have its source with Us; and nought do We bestow from on high unless it be in accordance with a measure well-defined. 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 It is We who give life and cause things to die and We are the sole Heirs. 23 And verily We know the eager among you and verily We know the laggards. 24 And indeed, your Lord will gather them; indeed, He is Wise and 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.
