It is He who sends down water from the sky. From it you drink and with it trees grow on which you pasture your cattle. 10 He causes to grow for you thereby the crops, olives, palm trees, grapevines, and from all the fruits. Indeed in that is a sign for a people who give thought. 11 And He has subjected for you the night and day and the sun and moon, and the stars are subjected by His command. Indeed in that are signs for a people who reason. 12 And what He has multiplied for you in the earth is of various hues; surely, in that there is a sign for a nation who remember. 13 It is He who subjected to you the sea, so that you may eat its fresh seafood and bring forth from it ornaments to wear. You see the ships cleaving through it. All this, so that you may seek His bounty and feel grateful. 14 He set firm mountains upon the earth lest it should shake with you; and rivers, and roads, in order that you are guided. 15 and He has set up other landmarks. By these and by the stars people set their course. 16 So, could one who creates be like one who cannot? Will you not then contemplate? 17 Even if you wanted to count up all of God's blessings, you would not be able to. God is All-forgiving and All-merciful. 18 And Allah knows what you conceal and what you declare. 19 Those whom they (Al-Mushrikun) invoke besides Allah have not created anything, but are themselves created. 20 They are, [in fact], dead, not alive, and they do not perceive 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.
