There is a sign in the dead earth for them which We quicken, and produce from it grain which they eat. 33 And We place therein gardens of the date-palms and vines; and We therein cause to gush forth springs. 34 so that they might eat of its fruit and the labor of their hands. Will they not give thanks? 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 withdraw therefrom the Day, and behold they are plunged in darkness; 37 And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise. 38 And for the moon We have appointed mansions till she return like an old shrivelled palm-leaf. 39 [and] neither may the sun overtake the moon, nor can the night usurp the time of day, since all of them float through space [in accordance with Our laws]. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 And We have created for them similar (vessels) on which they ride. 42 Had We wanted, We could have drowned them and nothing would have been able to help or rescue them 43 It is only by Our mercy that they are granted provision for a time. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 45 Indeed, not one of your Lord's signs comes to them without their turning away from it, 46 And when it is said to them: “Spend (in the Way of Allah) out of the sustenance that Allah has provided you,” the unbelievers say to the believers: “Shall we feed him whom, Allah would have fed, had He so wished?” Say: “You are in evident error.” 47 And they say: when will this promise be fulfilled if ye say sooth? 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 And they will not be able [to give] any instruction, nor to their people can they return. 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.
