A Sign for them is the earth that is dead: We do give it life, and produce grain therefrom, of which ye do eat. 33 And We produce therein orchard with date-palms and vines, and We cause springs to gush forth therein: 34 That they may eat of the fruit thereof, and their hands did not make it; will they not then be grateful? 35 All glory belongs to the One Who has created pairs out of what grow from the earth, out of their soul and out of that which they do not know. 36 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 And the sun runs on its fixed course for a term (appointed). That is the Decree of the All-Mighty, the All-Knowing. 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 catch up with the moon, nor does the night surpass the day; and each one of them floats in its orbit. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 and We have created for them the like of it whereon 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 except through Our Mercy and as enjoyment for awhile. 44 When they are told, "guard yourselves against what is before you and what is behind you, in order that you may be shown mercy," [they turn away]. 45 None of the signs of their Lord ever comes to them but they 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 And they say: "When will this promise come to pass, if what you say is true?" 48 They are only waiting for a single blast that will seize them, but they will go on contending. 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.
