There is a sign in the dead earth for them which We quicken, and produce from it grain which they eat. 33 And there We made gardens of palms and vines, and in it We caused fountains to gush forth, 34 that they might eat of its fruits and their hands' labour. What, will they not be thankful? 35 Glory be to Him Who created pairs of all things, of what the earth grows, and of their kind and of what 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 While the sun keeps revolving in its orbit. This is the dispensation of the mighty, all-knowing (God). 38 And the moon! For it We have decreed mansions till it reverteth like the old branch of a palm-tree. 39 It is not for the sun to catch up with the moon, nor does the night surpass the day; and each one of them floats in its orbit. 40 And a sign for them is that We carried their seed in the laden ship, 41 And We have created for them of the like thereunto whereon they ride. 42 and if We will, We drown them, then none have they to cry to, neither are they delivered, 43 Unless by Our benevolence, to reap advantage for a time. 44 When it is said to them: 'Have fear of that which is before you and behind you in order that you find mercy' 45 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 46 And when it is said unto them: expend of that wherewith Allah hath provided you, those who disbelieve say unto those who believe: shall we feed those whom God Himself would have fed, if He listed? Ye are in naught else than error manifest. 47 The unbelievers say, "When will the Day of Judgment come if what you say is at all true?" 48 They do not await except one blast which will seize them while they are disputing. 49 Then they will not be able to make a will or return to their families. 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.
