And a sign for them is the dead land, that We quickened and brought forth from it grain, whereof they 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 That they may eat of His fruit. And their hands have not produced it, so will they not 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 [they have a sign in] the sun: it runs in an orbit of its own [and] that is laid down by the will of the Almighty, 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 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, what they will ride on. 42 Had We wanted, We could have drowned them and nothing would have been able to help or rescue them 43 Except by way of Mercy from Us, and by way of (world) convenience (to serve them) for a time. 44 And when it is said unto them: fear that which is before you and that which is behind you, that haply ye may find mercy, they withdraw. 45 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 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 threat come to pass, if you are truthful? 48 They will not have to wait long. When the Day of Judgment comes, it will only take a single blast of sound to strike them while they are quarrelling with one another. 49 Therefore neither able to make a will, nor returning to their homes. 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.
