Did the unbelievers (who do not accept the teaching of the Prophet) not realize that the heavens and the earth were one solid mass, then We tore them apart, and We made every living being out of water? Will they, then, not believe (that We created all this)? 30 And We have set on the earth mountains standing firm, lest it should shake with them, and We have made therein broad highways (between mountains) for them to pass through: that they may receive Guidance. 31 And We have made the heavens as a canopy well guarded: yet do they turn away from the Signs which these things (point to)! 32 It is He Who created the night and the day, and the sun and the moon. Each of them is floating in its orbit. 33 We have never assigned immortality to a human before you, therefore, if you yourself die, will they live for ever? 34 Every living being must taste death; and We test you with harm and with good a trial; and to Us only you have to 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 is made of haste. I shall show you My portents, but ask Me not to hasten. 37 And they say: when cometh this torment if ye are truth-tellers! 38 If the unbelievers only knew when they will be unable to shield either their faces or their backs from the Fire; when they will not be helped! 39 Nay, it (the Fire or the Day of Resurrection) will come upon them all of a sudden and will perplex them, and they will have no power to avert it, nor will they get respite. 40 And already were messengers ridiculed before you, but those who mocked them were enveloped by what they used to ridicule. 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.
