There is a sign in the dead earth for them which We quicken, and produce from it grain which they eat. 33 And We have placed therein gardens of the date-palm and grapes, and We have caused springs of water to gush forth therein, 34 So that they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Exalted is He who created all pairs - from what the earth grows and from themselves and from that which they do not know. 36 And a sign for them is the night; We strip it of the day and lo, they are in darkness. 37 And the sun runs on to a term appointed for it; that is the ordinance of the Mighty, the Knowing. 38 We have ordained phases for the moon until finally it becomes like an old date-stalk. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 And a sign to them is that We bear their offspring in the laden ship. 41 and then created for them other vessels like those on which they ride. 42 Should We so wish, We can drown them, and there will be none to heed their cries of distress, nor will they be rescued. 43 save as a mercy from Us, and enjoyment for a while. 44 Whenever they are told to guard themselves against sin and the forth coming torment so that perhaps they could 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, 'Expend of that God has provided you,' the unbelievers say to the believers, 'What, shall we feed such a one whom, if God willed, He would feed? You are only in manifest error!' 47 The unbelievers say, "When will the Day of Judgment come if what you say is at all true?" 48 The Truth is that they are waiting for nothing but a mighty Blast to seize them the while they are disputing (in their worldly affairs), 49 then they will not be able to make any testament, nor will they return to their people. 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.
