اللَّهُمَّ أَرِنِي الْحَقَّ حَقًّا وَارْزُقْنِي اتِّبَاعَهُ وَأَرِنِي الْبَاطِلَ بَاطِلًا وَارْزُقْنِي اجْتِنَابَهُ
Allahumma arinal-haqqa haqqan warzuqnat-tiba'ah, wa arinal-batila batilan warzuqnaj-tinabah
O Allah, show me the truth as truth and grant me the ability to follow it, and show me falsehood as falsehood and grant me the ability to avoid it.
This du'a asks for two things: clarity of vision (to see truth and falsehood for what they are) and strength of will (to act accordingly). Many people can see the truth but lack the courage to follow it, or recognize evil but cannot resist it.
