It is He who gave you ears, eyes and hearts, yet how seldom you are grateful! 78 And He it is Who spread you on the earth, and unto Him ye will be gathered. 79 It is He who gives life, and makes to die, and to Him belongs the alternation of night and day; what, will you not understand? 80 No, but they said what the ancients said before them: 81 They say, "When we die and become dust and bones, shall we then be raised up again? 82 We and our fathers have been promised this before. It is but of the ancients' fictitious tales' 83 Say: "Whose is the earth and whosoever is therein? If you know!" 84 They will surely say: God's. Say thou: will ye not then heed? 85 Say: 'Who is the Lord of the seven heavens, and of the Great Throne' 86 They will say: "Allah." Say: "Will you not then fear Allah (believe in His Oneness, obey Him, believe in the Resurrection and Recompense for each and every good or bad deed)." 87 Say: "Who is it in whose hands is the governance of all things,- who protects (all), but is not protected (of any)? (say) if ye know." 88 They will surely say: "(The dominion over all things) belongs to Allah." Say: "Whence are you then deluded?" 89 In fact We brought the Truth to them, and indeed they are liars. 90 God has not taken to Himself any son, nor is there any god with Him; for then each god would have taken off that he created and some of them would have risen up over others; glory to be God, beyond that they describe, 91 Knower of the unseen and the seen, Exalted is He above that which they associate! 92

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.
