It is He who sends down rain from the sky: from it ye drink, and out of it (grows) the vegetation on which ye feed your cattle. 10 With which He makes crops grow, and olives, dates and grapes and fruits of every kind for you. In this is a sign for those who think. 11 And He subjected the night and the day for you and the sun and the moon; and the stars are subjected to His command; indeed in this are signs for people of intellect. 12 And the things He has created for you in the earth, of numerous colours; indeed in this is a sign for 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 placed mountains as anchors in the earth so that it may not shake along with you, and streams and roads for you to find course. 15 And also landmarks; and by the stars they are guided. 16 Is then the One Who creates like the one who does not create? Will you not, then, take heed? 17 And if you would count Allah's favors, you will not be able to number them; most surely Allah is Forgiving, Merciful. 18 God knows all that you conceal or reveal. 19 And those whom they call on besides Allah have not created anything while they are themselves created; 20 They are not living but are dead. They can not know 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.
