Human limitation in knowledge

۞ وَعِندَهُۥ مَفَاتِحُ ٱلْغَيْبِ لَا يَعْلَمُهَآ إِلَّا هُوَ ۚ وَيَعْلَمُ مَا فِى ٱلْبَرِّ وَٱلْبَحْرِ ۚ وَمَا تَسْقُطُ مِن وَرَقَةٍ إِلَّا يَعْلَمُهَا وَلَا حَبَّةٍ فِى ظُلُمَـٰتِ ٱلْأَرْضِ وَلَا رَطْبٍ وَلَا يَابِسٍ إِلَّا فِى كِتَـٰبٍ مُّبِينٍ

And with Him are the keys of the unseen; none knows them except Him. And He knows what is on the land and in the sea. Not a leaf falls but that He knows it. And no grain is there within the darknesses of the earth and no moist or dry [thing] but that it is [written] in a clear record.

قَالُوٓا۟ أَضْغَـٰثُ أَحْلَـٰمٍ ۖ وَمَا نَحْنُ بِتَأْوِيلِ ٱلْأَحْلَـٰمِ بِعَـٰلِمِينَ

They said, "[It is but] a mixture of false dreams, and we are not learned in the interpretation of dreams."
