Have not those who disbelieve known that the heavens and the earth were of one piece, then We parted them, and we made every living thing of water? Will they not then believe? 30 And We have placed in the earth firm mountains lest it should move away with them, and We placed therein passages for paths, that haply they may be guided. 31 We have made the heaven a well-secured canopy; yet still they turn away from Our signs. 32 It is God who has created the night, the day, the Sun, and Moon and has made them swim in a certain orbit. 33 And We did not ordain abiding for any mortal before you. What! Then if you die, will they abide? 34 Every soul shall taste death. We will try you with a trial of evil and good. Then, to Us you shall 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 is a creature of haste: soon (enough) will I show you My Signs; then ye will not ask Me to hasten them! 37 And they say: When will this threat come to pass if you are truthful? 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 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 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.
