Upon encountering an enemy or those of authority #1

اَللّٰهُمَّ إِنَّا نَجْعَلُكَ فِيْ نُحُوْرِهِم، وَنَعُوْذُ بِكَ مِنْ شُرُوْرِهِمْ

O Allah, we ask You to restrain them by their necks and we seek refuge in You from their evil.

Allaahumma 'innaa naj'aluka fee nuhoorihim wa na'oothu bika min shuroorihim.
