Divine wisdom and hidden knowledge

وَكَيْفَ تَصْبِرُ عَلَىٰ مَا لَمْ تُحِطْ بِهِۦ خُبْرًا

And how can you have patience for what you do not encompass in knowledge?"

قَالَ إِن سَأَلْتُكَ عَن شَىْءٍۭ بَعْدَهَا فَلَا تُصَـٰحِبْنِى ۖ قَدْ بَلَغْتَ مِن لَّدُنِّى عُذْرًا

[Moses] said, "If I should ask you about anything after this, then do not keep me as a companion. You have obtained from me an excuse."

فَٱنطَلَقَا حَتَّىٰٓ إِذَآ أَتَيَآ أَهْلَ قَرْيَةٍ ٱسْتَطْعَمَآ أَهْلَهَا فَأَبَوْا۟ أَن يُضَيِّفُوهُمَا فَوَجَدَا فِيهَا جِدَارًا يُرِيدُ أَن يَنقَضَّ فَأَقَامَهُۥ ۖ قَالَ لَوْ شِئْتَ لَتَّخَذْتَ عَلَيْهِ أَجْرًا

So they set out, until when they came to the people of a town, they asked its people for food, but they refused to offer them hospitality. And they found therein a wall about to collapse, so he [i.e., al-Khiḍr] restored it. [Moses] said, "If you wished, you could have taken for it a payment."

فَأَرَدْنَآ أَن يُبْدِلَهُمَا رَبُّهُمَا خَيْرًا مِّنْهُ زَكَوٰةً وَأَقْرَبَ رُحْمًا

So we intended that their Lord should substitute for them one better than him in purity and nearer to mercy.
