AND NEVER YET have We sent a prophet unto any community without trying its people with misfortune and hardship, so that they might humble themselves; 94 Thereafter We substituted ease in place of adversity until they abounded and said: even Thus tribulation and prosperity touched our fathers. Then We laid hold of them of a sudden, while they perceived not. 95 Yet if the people of those communities had but attained to faith and been conscious of Us, We would indeed have opened up for them blessings out of heaven and earth: but they gave the lie to the truth - and so We took them to task through what they [themselves] had been doing. 96 Do the inhabitants of the villages feel secure from Our Might coming to them at night whilst they sleep? 97 Or, did the people of the towns then feel secure against the coming of Our Punishment in the forenoon while they play? 98 Do they feel secure against God's devising? None feels secure against God's devising but the people of the lost. 99

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.
