Seest thou not that it is Allah Whose praises all beings in the heavens and on earth do celebrate, and the birds (of the air) with wings outspread? Each one knows its own (mode of) prayer and praise. And Allah knows well all that they do. 41 And Allah's is the dominion of the heavens and the earth, and unto Allah is the return. 42 Do you not see that Allah drives clouds? Then He brings them together, then He makes them into a mass, and you see the rain emerge from within it. And He sends down from the sky, mountains [of clouds] within which is hail, and He strikes with it whom He wills and averts it from whom He wills. The flash of its lightening almost takes away the eyesight. 43 God alternates the night and the day. In this there is a lesson for the people of understanding. 44 God created every creature from water. Some crawl upon their bellies, others walk on two legs, and others walk on four. God creates what He pleases. He has power over all things. 45 Assuredly We have sent down revelations illuminating: and Allah guideth whomsoever He listeth unto a path straight. 46 And they say: We believe in Allah and in the apostle and we obey; then a party of them turn back after this, and these are not believers. 47 When they are summoned to Allah and His messenger, in order that He may judge between them, behold some of them decline (to come). 48 If the right is theirs, they would have hastened to him obediently. 49 Are their hearts diseased, or do they have doubts, or do they fear that Allah and His Noble Messenger will oppress them? In fact they themselves are the unjust. 50

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.
