And a sign unto them is the dead land. We quicken it and thereout We bring forth grain, so that thereof they eat. 33 And We make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 That they may enjoy the fruits of this (artistry): It was not their hands that made this: will they not then give thanks? 35 Glory be to Him Who created all the sexual pairs, of that which the earth groweth, and of themselves, and of that which they know not! 36 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 how the sun moves in its orbit and this is the decree of the Majestic and All-knowing God; 38 We have ordained phases for the moon until finally it becomes like an old date-stalk. 39 It is not for the sun to overtake the moon, nor does the night outstrip the day. They all float, each in an orbit. 40 And [it ought to be] a sign for them that We bear their offspring [over the seas] in laden ships, 41 And We have created for them the like of it in which they board. 42 And if We please, We can drown them, then there shall be no succorer for them, nor shall they be rescued 43 Unless it be a mercy from Us, and as an enjoyment for a while. 44 When it is said to such people: “Guard yourselves against what is ahead of you and what has preceded you that mercy be shown to you” (they pay scant heed to it). 45 Yet there never comes to them any sign of their Lord's signs, but they turn away from it. 46 When they are told: "Spend of what God has given you," the unbelievers say to those who believe: "Why should we feed those whom God should have fed if He pleased?" You are only in palpable error. 47 And they say, “When will this promise be fulfilled, if you are truthful?” 48 They await only but a single Saihah (shout, etc.), which will seize them while they are disputing! 49 Then they will be unable to make a will, nor shall they return to their kinsmen. 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.
