﴿ أُو۟لَٰٓئِكَ ٱلَّذِينَ لَعَنَهُمُ ٱللَّهُ فَأَصَمَّهُمْ وَأَعْمَىٰٓ أَبْصَٰرَهُمْ ﴾

“It is such as these whom God rejects, and whom He makes deaf [to the voice of truth], and whose eyes He blinds [to its sight]!”

Those that is the agents of corruption are the ones whom God has cursed so made them deaf to hearing the truth and blinded their eyes to the path of guidance.
