Al-Adab Al-Mufrad 481

Abu Hurayra reported that the Prophet ﷺ said, "There are three supplications which are answered:
the supplication of the person who is wronged, the supplication of the traveller, and the supplication of a parent for his child.

حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ: حَدَّثَنَا شَيْبَانُ، عَنْ يَحْيَى، عَنْ أَبِي جَعْفَرٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ ﷺ قَالَ: ثَلاَثُ دَعَوَاتٍ مُسْتَجَابَاتٍ: دَعْوَةُ الْمَظْلُومِ، وَدَعْوَةُ الْمُسَافِرِ، وَدَعْوَةُ الْوَالِدِ عَلَى وَلَدِهِ.
