It is He Who sent down water from the sky you drink from it, and from it are trees you use as pasture. 10 and by virtue of which He causes crops and olives and date-palms and grapes and all kinds of fruit to grow for you. Surely in this there is a great Sign for those who reflect. 11 He has made subject to you the Night and the Day; the sun and the moon; and the stars are in subjection by His Command: verily in this are Signs for men who are wise. 12 And He hath subjected for you whatsoever He hath multiplied for you on the earth of various kinds. Verily therein is a sign for a people who receive admonition. 13 And He it is Who hath constrained the sea to be of service that ye eat fresh meat from thence, and bring forth from thence ornaments which ye wear. And thou seest the ships ploughing it that ye (mankind) may seek of His bounty and that haply ye may give thanks. 14 God has fixed the mountains on earth lest you should be hurled away when it quakes. Therein He has also made rivers and roads so that you will find your way. 15 and He has set other landmarks in the earth. And by the stars too do people find their way. 16 Is then He Who creates like one that creates not? Will ye not receive admonition? 17 And if you should count the favors of Allah, you could not enumerate them. Indeed, Allah is Forgiving and Merciful. 18 And Allah doth know what ye conceal, and what ye reveal. 19 And those whom they worship other than Allah, do not create anything but are themselves created. 20 Dead (are they), not living, and they know not when they shall be raised. 21

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.
