Corruptness hath appeared on land and sea because of that which men's hands have earned, so that he may make them taste a part of that which they have worked, in order that haply they may turn. 41 Say: "Travel through the earth and see what was the end of those before (you): Most of them worshipped others besides Allah." 42 Set, then, thy face steadfastly towards the one ever-true faith, ere there come from God a Day [of reckoning - the Day] which cannot be averted. On that Day all will be sundered: 43 Whoever disbelieves, then the calamity of his disbelief is only on him; and those who do good deeds, are preparing for themselves. 44 God will reward the righteously striving believers through His favor. He does not love the unbelievers. 45 And among His Signs is this, that He sends the winds as glad tidings, giving you a taste of His Mercy (i.e. rain), and that the ships may sail at His Command, and that you may seek of His Bounty, in order that you may be thankful. 46 And assuredly We sent apostles before thee unto their people. They brought them manifest signs. Then We took vengeance upon those who transgressed. And incumbent upon us was avengement of the believers. 47 It is Allah Who sends the winds raising the clouds therefore spreads them in the sky as He wills and shatters them so you see the rain dropping from inside it; so when He delivers it upon whomever He wills among His bondmen, thereupon they rejoice. 48 Although they had lost hope before it was sent down upon them. 49 Behold, then, [O man,] these signs of God's grace - how He gives life to the earth after it had been lifeless! Verily, this Selfsame [God] is indeed the One that can bring the dead back to life: for He has the power to will anything! 50 And if We send a wind [which would spoil the green growth (tilth) brought up by the previous rain], and they see (their tilth) turn yellow, behold, they then after their being glad, would become unthankful (to their Lord Allah as) disbelievers. 51 So verily thou canst not make the dead hear, nor canst thou make the deaf hear the call when they turn away in flight. 52 just as thou canst not lead the blind [of heart] out of their error: none canst thou make hear [thy call] save such as [are willing to] believe in Our messages, and thus surrender themselves unto Us. 53

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.
