Ibn al-Hanba’ reported: Ali, may Allah be pleased with him, said, “Three supplications are never turned away: a just leader for his subjects, a parent over his child, and the supplication of the oppressed.”

عَنِ ابْنِ الْحَبْنَاءِ التَّمِيمِيِّ عَنْ عَلِيٍّ رضي الله عنه قَالَ ثَلَاثَةٌ لَا تُرَدُّ دَعْوَتَهُمُ الْإِمَامُ الْعَادِلُ عَلَى رَعِيَّتِهِ وَالْوَالِدُ عَلَى وَلَدِهِ وَدَعْوَةُ الْمَظْلُومِ
