And indeed We created towers in the skies, and beautified it for the beholders. 16 and have protected them against every accursed satan 17 save him who may eavesdrop, and then a bright flame pursues him. 18 And the earth We spread out, and placed therein firm mountains, and caused to grow therein all kinds of things in due proportion. 19 to provide you and those for whose sustenance you are not responsible, with the necessities of life. 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 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 most surely We bring to life and cause to die and We are the heirs. 23 We know those of you who press forward, and We know the laggards, 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.
