Hadith
عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم بَعَثَ مُعَاذًا إِلَى الْيَمَنِ، فَقَالَ
اتَّقِ دَعْوَةَ الْمَظْلُومِ، فَإِنَّهَا لَيْسَ بَيْنَهَا وَبَيْنَ اللَّهِ حِجَابٌ
ر واه البخاري ٢٤٤٨
Narrated Ibn `Abbas:
The Prophet (ﷺ) sent Mu`adh to Yemen and said,
“Be afraid, from the curse of the oppressed as there is no screen between his invocation and Allah.”
Sahih al-Bukhari 2448
