And a sign for them is the dead earth. We have brought it to life and brought forth from it grain, and from it they eat. 33 And We placed therein gardens of palm trees and grapevines and caused to burst forth therefrom some springs - 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 created all the pairs of what the earth produces, and of themselves, and of what they know not. 36 And a sign for them is the night. We remove from it [the light of] day, so they are [left] in darkness. 37 The sun runs to its fixed resting place; that is the decree of the Almighty, the Knower. 38 We have ordained phases for the moon until finally it becomes like an old date-stalk. 39 how the sun is not supposed to catch-up with the moon, nor is the night to precede the day. All of them are to float in a certain orbit; 40 Another sign for them is that We carried their offspring in the laden Ark. 41 And We have created for them similar ships, in which they now ride. 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 43 It is only by Our mercy that they are granted provision for a time. 44 When it is said to them: 'Have fear of that which is before you and behind you in order that you find mercy' 45 yet never any sign of the signs of their Lord comes to them, but they are turning away from it. 46 and when they are told, "Give to others out of what God has provided for you," those who are bent on denying the truth say to the believers, "Why should we feed those whom God could feed if He wanted? You are clearly in error!" 47 And they say: When will this promise be fulfilled, if ye 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 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.
