[Prophet], do you not see that all those who are in the heavens and on earth praise God, as do the birds with wings outstretched? Each knows his own mode of prayer and glorification: God has full knowledge of all that they do. 41 Yea, to Allah belongs the dominion of the heavens and the earth; and to Allah is the final goal (of all). 42 Do you not see how God drives the clouds, then joins them together, then piles them into layers and then you see the rain pour from their midst? He sends down from the skies mountainous masses [of clouds] charged with hail, and He makes it fall on whom He will, and turns it away from whom He pleases. The flash of His lightning may well-nigh take away the sight. 43 Allah causeth the revolution of the day and the night. Lo! herein is indeed a lesson for those who see. 44 God created every moving thing from water: One crawls on its belly, one walks on two legs, another moves on four. God creates whatsoever He will. Indeed God has power over everything. 45 We have sent down clarifying verses. Allah guides whom He will to a Straight Path. 46 And they say: We believe in Allah and the messenger, and we obey; then after that a faction of them turn away. Such are not believers. 47 And when they are called to Allah (i.e. His Words, the Quran) and His Messenger (SAW), to judge between them, lo! a party of them refuse (to come) and turn away. 48 But if the truth happens to be to their liking, they are quite willing to accept it! 49 What, is there sickness in their hearts, or are they in doubt, or do they fear that God may be unjust towards them and His Messenger? Nay, but those -- they are the evildoers. 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.
