Du'a for fear: O Allah, we place You before them

اللَّهُمَّ إِنَّا نَجْعَلُكَ فِي نُحُورِهِمْ وَنَعُوذُ بِكَ مِنْ شُرُورِهِمْ

Allahumma inna naj'aluka fi nuhurihim, wa na'udhu bika min shururihim.

O Allah, we place You before them (those who intend harm) and we seek refuge in You from their evils.

Sunan Abī Dāwūd 1537
