Did not the disbelievers observe that the heavens and the earth were together, so We parted them, and we made every living thing from water? So will they not accept faith? 30 And We have placed in the earth firm hills lest it quake with them, and We have placed therein ravines as roads that haply they may find their way. 31 And We made the sky a protected ceiling, but they, from its signs, are turning away. 32 And it is He Who created the night and the day, and the sun and the moon; each one floats in an orbit. 33 We appointed immortality for no mortal before thee. What! if thou diest, can they be immortal! 34 Everyone is going to taste death, and We shall make a trial of you with evil and with good, and to Us you will be returned. 35 But when the unbelievers see you they make fun of you (and say): "Is this the one who mentions your gods (deridingly)?" Yet in Ar-Rahman they disbelieve! 36 Man was created of haste. Assuredly I shall show you My signs; so demand not that I make haste. 37 They say, 'And when shall the promise come to pass, if you speak truly?' 38 If only the unbelievers could apprehend the moment when they would neither be able to ward off the fire from their faces and their backs, nor help reach them! 39 It will come upon them unawares confounding them, and they will not be able to keep it back, nor will they be given respite. 40 Messengers indeed were mocked at before thee, but those that scoffed at them were encompassed by that they mocked at. 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.
