Divine knowledge versus human limitation

ذَٰلِكَ مِنْ أَنۢبَآءِ ٱلْغَيْبِ نُوحِيهِ إِلَيْكَ ۚ وَمَا كُنتَ لَدَيْهِمْ إِذْ يُلْقُونَ أَقْلَـٰمَهُمْ أَيُّهُمْ يَكْفُلُ مَرْيَمَ وَمَا كُنتَ لَدَيْهِمْ إِذْ يَخْتَصِمُونَ

That is from the news of the unseen which We reveal to you, [O Muḥammad]. And you were not with them when they cast their pens as to which of them should be responsible for Mary. Nor were you with them when they disputed.

وَلَآ أَقُولُ لَكُمْ عِندِى خَزَآئِنُ ٱللَّهِ وَلَآ أَعْلَمُ ٱلْغَيْبَ وَلَآ أَقُولُ إِنِّى مَلَكٌ وَلَآ أَقُولُ لِلَّذِينَ تَزْدَرِىٓ أَعْيُنُكُمْ لَن يُؤْتِيَهُمُ ٱللَّهُ خَيْرًا ۖ ٱللَّهُ أَعْلَمُ بِمَا فِىٓ أَنفُسِهِمْ ۖ إِنِّىٓ إِذًا لَّمِنَ ٱلظَّـٰلِمِينَ

And I do not tell you that I have the depositories [containing the provision] of Allāh or that I know the unseen, nor do I tell you that I am an angel, nor do I say of those upon whom your eyes look down that Allāh will never grant them any good. Allāh is most knowing of what is within their souls. Indeed, I would then be among the wrongdoers [i.e., the unjust]."
