And a sign for them is the dead land. We gave it life, and We brought forth from it grains, so that they eat thereof. 33 And We make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 So that they may eat from its fruits, whereas they are not manufactured by their hands! So will they not be grateful? 35 All glory to Him who created pairs of everything that grows from the earth, and out of themselves, and other things they do not know. 36 And a sign for them is the night; We strip the day out of it, thereupon they are in darkness. 37 And the sun runs his course for a period determined for him: that is the decree of (Him), the Exalted in Might, the All-Knowing. 38 And the moon! For it We have decreed mansions till it reverteth like the old branch of a palm-tree. 39 The sun cannot overtake the moon, nor can the night outpace the day: each floats in [its own] orbit. 40 And a Sign for them is that We bore their race (through the Flood) in the loaded Ark; 41 And We have created for them similar (vessels) on which they ride. 42 and if We will, We drown them, then none have they to cry to, neither are they delivered, 43 except through Our Mercy and as enjoyment for awhile. 44 But when it is said to them, "Beware of what is before you and what is behind you; perhaps you will receive mercy... " 45 And never came an Ayah from among the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of their Lord to them, but they did turn away from it. 46 And when it is said to them: 'Spend of that which Allah has given you' the unbelievers say to the believers: 'Are we to feed those whom Allah can feed if He chooses? Surely, you are only in clear error' 47 And they say: when will this promise be fulfilled if ye say sooth? 48 They do not await except one blast which will seize them while they are disputing. 49 Therefore neither able to make a will, nor returning to their homes. 50

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.
