Concealment of knowledge for wisdom

۞ قَالُوٓا۟ إِن يَسْرِقْ فَقَدْ سَرَقَ أَخٌ لَّهُۥ مِن قَبْلُ ۚ فَأَسَرَّهَا يُوسُفُ فِى نَفْسِهِۦ وَلَمْ يُبْدِهَا لَهُمْ ۚ قَالَ أَنتُمْ شَرٌّ مَّكَانًا ۖ وَٱللَّهُ أَعْلَمُ بِمَا تَصِفُونَ

They said, "If he steals - a brother of his has stolen before." But Joseph kept it within himself and did not reveal it to them. He said, "You are worse in position, and Allāh is most knowing of what you describe."
