عن بن عَبَّاسٍ رضي الله عنهما أَنَّ النبي صلى الله عليه وسلم بَعَثَ مُعَاذًا إلى الْيَمَنِ فقال اتَّقِ دَعْوَةَ الْمَظْلُومِ فَإِنَّهَا ليس بَيْنَهَا وَبَيْنَ اللَّهِ حِجَابٌ

Abdullah ibn ‘Abbas (rta) reports that when the Prophet (sws) sent Mu‘adh ibn Jabal (rta) to Yemen [as its administrator] he said: “Beware of the pleading of an oppressed person because there is no obstruction between it and God.”[1]
