It is He who sends down water from the sky of which you drink, and which nourishes the plants you feed 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 hath subjected for you the night and the day and the sun and the moon, and the stars are subjected by His command. Verily therein are signs for a people who understand. 12 And what He has created in the earth of varied hues most surely there is a sign in this for a people who are mindful. 13 It is He who has subdued the sea that you may eat fresh meat from it, and obtain ornaments to wear. You see the ships plough through it that you may seek of His bounties and, perhaps, be grateful. 14 And He has placed firm mountains on the earth lest it should move away from you, and has made rivers and tracks that you may find your way, 15 And marks and sign-posts; and by the stars (men) guide themselves. 16 Then is He who creates like one who does not create? So will you not be reminded? 17 If you count the favors of Allah, you could not number them. Indeed, Allah is Forgiving and the Most Merciful. 18 And Allah knoweth that which ye keep hidden and that which ye proclaim. 19 Those unto whom they cry beside Allah created naught, but are themselves created. 20 they are dead, not living. They do not even know when they will be resurrected. 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.
