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 produced therein grains from which they eat and established therein gardens of palms trees and vineyards and have made streams flow therein 34 so that they may eat its fruit, though it was not their hands that made this. Will they not then be grateful? 35 Glory be to Him, Who has created all the pairs of that which the earth produces, as well as of their own (human) kind (male and female), and of that which they know not. 36 Of the signs for them is how We separated the day from the night and thus they remained 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 the moon -- We have determined it by stations, till it returns like an aged palm-bough. 39 Neither is it allowable to the sun that it should overtake the moon, nor can the night outstrip the day; and all float on in a sphere. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 We have created for them the like of it in which they ride. 42 If it were Our will, We could drown them: then there would be no helper [to hear their cry], nor could they be saved. 43 It is only Our Mercy (that rescues them) and enables enjoyment of life for a while. 44 And when it is said to them, “Beware of what is before you and what is behind you, in the hope of your gaining mercy”, they turn away! 45 And no sign comes to them from the signs of their Lord except that they are from it turning away. 46 Thus, when they are told, "Spend on others out of what God has provided for you as sustenance," those who are bent on denying the truth say unto those who believe, "Shall we feed anyone whom, if [your] God had so willed, He could have fed [Himself]? Clearly, you are but lost in error!" 47 And they say: When will this threat come to pass, if you are truthful? 48 They are awaiting only for one Cry to seize them while they are yet 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.
