And [mention] when Moses said to his servant, "I will not cease [traveling] until I reach the junction of the two seas or continue for a long period." 60 So when they had reached the junction of the two (rivers) they forgot their fish, and it took its way into the sea, going away. 61 So when they had passed beyond it, [Moses] said to his boy, "Bring us our morning meal. We have certainly suffered in this, our journey, [much] fatigue." 62 He replied: 'What do you think, I forgot the fish when we were resting on the rock. None but satan made me forget to mention this; it made its way into the sea in a marvelous fashion' 63 Said Moosa, “This is exactly what we wanted”; so they came back retracing their steps. 64 Then they found one from among Our servants whom We had granted mercy from Us and whom We had taught knowledge from Ourselves. 65 Moses said to him: 'May I follow you so that you can teach me of that you have learned of righteousness' 66 He (Khidr) said: "Verily! You will not be able to have patience with me! 67 How could you be patient in matters beyond your knowledge?" 68 He said, 'Yet thou shalt find me, if God will, patient; and I shall not rebel against thee in anything.' 69 The other said: "If then thou wouldst follow me, ask me no questions about anything until I myself speak to thee concerning it." 70

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.
