limits of human understanding

قَالَ إِنَّكَ لَن تَسْتَطِيعَ مَعِىَ صَبْرًا

He said, "Indeed, with me you will never be able to have patience.

قَالَ سَتَجِدُنِىٓ إِن شَآءَ ٱللَّهُ صَابِرًا وَلَآ أَعْصِى لَكَ أَمْرًا

[Moses] said, "You will find me, if Allāh wills, patient, and I will not disobey you in [any] order."

وَأَمَّا ٱلْغُلَـٰمُ فَكَانَ أَبَوَاهُ مُؤْمِنَيْنِ فَخَشِينَآ أَن يُرْهِقَهُمَا طُغْيَـٰنًا وَكُفْرًا

And as for the boy, his parents were believers, and we feared that he would overburden them by transgression and disbelief.
