It is He who sends down to you out of heaven water of which you have to drink, and of which trees, for you to pasture your herds, 10 [and] by virtue thereof He causes crops to grow for you, and olive trees, and date palms, and grapes, and all [other] kinds of fruit: in this, behold, there is a message indeed for people who think! 11 And He has subjected for you the night and day and the sun and moon, and the stars are subjected by His command. Indeed in that are signs for a people who reason. 12 On the earth He has fashioned for you objects of various hues: there is certainly a sign in that for people who pay heed. 13 And it is He who subjected the sea for you to eat from it tender meat and to extract from it ornaments which you wear. And you see the ships plowing through it, and [He subjected it] that you may seek of His bounty; and perhaps you will be grateful. 14 And He hath cast on the earth firm mountains lest it move away with you, and rivers and paths that haply ye may be directed. 15 And marks and sign-posts; and by the stars (men) guide themselves. 16 Is then He, Who creates as one who creates not? Will you not then remember? 17 If you count the favours of God you will not be able to calculate. Assuredly God is forgiving and kind. 18 And Allah knows what you conceal and what you reveal. 19 , As for those they call besides God, they cannot create a thing, and have themselves been created. 20 (They are) dead, not living. And they know not when they will be raised. 21

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.
