It is He who sends down water from heaven, which provides drink for you and brings forth trees on which your herds feed. 10 With this water He produces for you crops, and olives, and dates, and grapes, and all kinds of fruit; indeed in this is a sign for 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 [He has subjected] whatever He multiplied for you on the earth of varying colors. Indeed in that is a sign for a people who remember. 13 And it is He Who subjected the sea for you, so you eat fresh meat from it, and extract ornaments from it which you wear; and you see ships ploughing through it and in order that you may seek His munificence and that you may give thanks. 14 And He has cast great mountains in the earth lest it might be convulsed with you, and rivers and roads that you may go aright, 15 and waymarks; and by the stars they are guided. 16 IS, THEN, HE who creates comparable to any [being] that cannot create? Will you not, then, bethink yourselves? 17 And if you enumerate the favours of Allah, you will never be able to count them; indeed Allah is Oft Forgiving, Most Merciful. 18 And Allah doth know what ye conceal, and what ye reveal. 19 Those unto whom they cry beside Allah created naught, but are themselves 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.
