If there is some problem which is not being resolved and you are facing some ill-mannered person, while on your way to meet him,  keep reciting the following prayer by the quantity in odd numbers. His heart will be softened for you and he will behave with gratitude. I have repeatedly tried this prayer.

Prayer: Allahuma inna Naja’luka fee Nuhurihim Wa Na’uzubika min Shururihim.

اَللّٰھُمَّ اِنَّانَجْعَلُکَ فِیْ نُحُوْرِھِمْ وَنَعُوْذُبِکَ مِنْ شُرُوْرِھِمْ

(Amjad Iqbal, Attock)
