And of His signs is that He created you of dust; then lo, you are mortals, all scattered abroad. 20 And one of His signs is that He created mates for you from yourselves that you may find rest in them, and He put between you love and compassion; most surely there are signs in this for a people who reflect. 21 And one of His signs is the creation of the heavens and the earth and the diversity of your tongues and colors; most surely there are signs in this for the learned. 22 And of His signs is that you sleep at night and day, and seek His bounty. Surely, there are signs in this for those who hear. 23 Among His signs is this: He shows you the lightning, giving rise to [both] fear and hope, and sends down water from the sky, giving life thereby to the earth after it had been lifeless: in this, behold, there are signs indeed for people who use their reason! 24 And of His signs is this: The heavens and the earth stand fast by His command, and afterward, when He calleth you, lo! from the earth ye will emerge. 25 All those who are in the heavens and the earth are His, and they are all obedient to Him. 26 It is He who first creates and then reverts it. This is how His law works inevitably. His semblance is of the most sublime in the heavens and the earth. He is all-mighty and all-wise. 27

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.
