Sahih (Al-Albani)
Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, 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 صلى الله عليه وسلم قَالَ: ثَلاَثُ دَعَوَاتٍ مُسْتَجَابَاتٍ: دَعْوَةُ الْمَظْلُومِ، وَدَعْوَةُ الْمُسَافِرِ، وَدَعْوَةُ الْوَالِدِ عَلَى وَلَدِهِ
