Dua When Someone Insults You

رَبِّ احْكُم بِالْحَقِّ ۗ وَرَبُّنَا الرَّحْمَٰنُ الْمُسْتَعَانُ عَلَىٰ مَا تَصِفُونَ

Rabbi ohkum bilhaqqi wa rabbuna arrahmanul musta'aanu alaa ma tasifoon

Pronunciation: My Lord, judge [between us] in truth. And our Lord is the Most Merciful, the one whose help is sought against that which you describe.

Reference: Surah Al-Anbiya - 21:112
