Indeed, We sent Nuh (Noah) to his people and he said: "O my people! Worship Allah! You have no other Ilah (God) but Him. (La ilaha ill-Allah: none has the right to be worshipped but Allah). Certainly, I fear for you the torment of a Great Day!" 59 But the assembly of his nation said: 'We can see that you are in clear error.' 60 Said he, 'My people, there is no error in me; but I am a Messenger from the Lord of all Being.' 61 I am delivering unto you my Sustainer's messages and giving you good advice: for I know [through revelation] from God what you do not know. 62 Do you wonder that admonition should come to you from your Lord through a man from amongst yourselves that he may warn you, that you may avoid evil and that mercy may be shown to you?' 63 But they called him a liar, and We saved him and those with him in the Ark, and drowned the others who rejected Our signs, for they were a people purblind. 64

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.
