And We have placed within the heaven great stars and have beautified it for the observers. 16 and guarded them from every stoned satan. 17 Save him who stealeth the hearing, and him there followeth a flame gleaming. 18 And the earth - We have spread it and cast therein firmly set mountains and caused to grow therein [something] of every well-balanced thing. 19 and there appointed for you is a livelihood, and for those you do not provide. 20 And there is not a thing, but with Us are the stores thereof. And We send it not down except in a known measure. 21 And We send the winds fertilizing, then send down water from the cloud so We give it to you to drink of, nor is it you who store it up. 22 And verily We! it is We who give life and death, and We shall be the survivors. 23 And assuredly We know those of you who have gone before and those who will come hereafter. 24 It is your Lord who will gather them. He is all wise and all knowing. 25

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.
