Do not those who disbelieve see that the heavens and the earth were closed up, but We have opened them; and We have made of water everything living, will they not then believe? 30 We placed stabilisers in the earth so that as it revolved with them you lived undisturbed; and We provided passageways between them so that men may find their way; 31 We established the heaven as a well protected roof, yet they still turn away from its signs. 32 And He it is Who created the night and the day, and the sun and the moon. They float, each in an orbit. 33 (O Muhammad), We did not grant everlasting life to any human being even before you. If you were to die, will they live for ever? 34 Every soul will know the taste of death. We tempt you with evil and with good as a trial; and to Us you will return. 35 When the unbelievers see you they make you an object of fun, saying: "Is he the one who mentions your gods?" They say so, and yet they reject with disdain the very mention of the Most Compassionate Lord. 36 Man has been created hasty; very soon I shall show you My signs, do not be impatient. 37 They ask, "When will this promise be fulfilled, if what you say be true?" 38 If only those who disbelieved knew (the time) when they will not be able to ward off the Fire from their faces, nor from their backs; and they will not be helped. 39 That will suddenly come upon them and stupefy them. They shall not be able to ward it off, nor shall they be granted any respite. 40 Messengers before thee, indeed, were mocked, but that whereat they mocked surrounded those who scoffed at them. 41

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.
