He it is Who sendeth down water from the sky, whence ye have drink, and whence are trees on which ye send your beasts to pasture. 10 He groweth for you thereby the corn and olives and date-palms and grapes and all kinds of fruit. Verily therein is a sign for a people who ponder. 11 And He has subjected to you the night and the day, the sun and the moon; and the stars are subjected by His Command. Surely, in this are proofs for people who understand. 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 has made the sea subservient that you may eat fresh flesh from it and bring forth from it ornaments which you wear, and you see the ships cleaving through it, and that you might seek of His bounty and that you may give thanks. 14 He placed stablisers in the earth so that while it revolves you live undisturbed, and rivers and tracks so that you may find your way; 15 as well as [various other] means of orientation: for [it is] by the stars that men find their way. 16 Is He who creates as he who does not create? Will you not remember? 17 And if ye would count the favours of Allah ye could not compute them; verily Allah is Forgiving, Merciful. 18 And God knows what you keep secret and what you publish. 19 Now those beings that some people invoke beside God cannot create anything, since they themselves are but created: 20 They are dead, not living; nor do they know when they will be raised to life. 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.
