He it is Who sends down water for you from the sky out of which you drink and out of which grow the plants on which you pasture your cattle, 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 made subservient for you the night and the day and the sun and the moon, and the stars are made subservient by His commandment; most surely there are signs in this for a people who ponder; 12 And whatsoever He hath created for you in the earth of divers hues, lo! therein is indeed a portent for people who take heed. 13 And He it is who hath subjected the sea that ye may eat thereout flesh fresh and bring forth therefrom ornaments that ye wear. And thou beholdest ships ploughing therein, and it is in order that ye may seek of His grace, and that haply ye may give thanks. 14 And He has set up on the earth mountains standing firm, lest it should shake with you; and rivers and roads; that ye may guide yourselves; 15 and waymarks; and by the stars they are guided. 16 Is He, then, who creates like him who does not create? Will you not, then, take heed? 17 And if ye would count the favours of Allah ye could not compute them; verily Allah is Forgiving, Merciful. 18 God knows all that you conceal or reveal. 19 , As for those they call besides God, they cannot create a thing, and have themselves been created. 20 They are dead, not alive; and they do not know when will the people 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.
