حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنْ سَعْدَانَ الْجُهَنِيِّ، عَنْ سَعْدٍ أَبِي مُجَاهِدٍ الطَّائِيِّ، - وَكَانَ ثِقَةً - عَنْ أَبِي مُدِلَّةَ، - وَكَانَ ثِقَةً - عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ ثَلاَثَةٌ لاَ تُرَدُّ دَعْوَتُهُمُ الإِمَامُ الْعَادِلُ وَالصَّائِمُ حَتَّى يُفْطِرَ وَدَعْوَةُ الْمَظْلُومِ يَرْفَعُهَا اللَّهُ دُونَ الْغَمَامِ يَوْمَ الْقِيَامَةِ وَتُفْتَحُ لَهَا أَبْوَابُ السَّمَاءِ وَيَقُولُ بِعِزَّتِي لأَنْصُرَنَّكِ وَلَوْ بَعْدَ حِينٍ ‏"‏ ‏.‏

It wasnarrated from Abu Hurairah that the Messenger of Allah (ﷺ)said

There are three whose supplications are not turned back: A justruler, and a fasting person until he breaks his fast. And, thesupplication of one who has been wronged is raised by Allah up to theclouds on the Day of Resurrection, and the gates of heaven are openedfor it, and Allah says, ‘By My Might I will help you (against thewrongdoer) even if it is after a while.’”
