Narrated AbuHurayrah:

The Prophet ﷺ said: Three supplications are answered, there being no doubt about them; that of a father, that of a traveller and that of one who has been wronged.

حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هِشَامٌ الدَّسْتَوَائِيُّ، عَنْ يَحْيَى، عَنْ أَبِي جَعْفَرٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ ﷺ قَالَ " ثَلاَثُ دَعَوَاتٍ مُسْتَجَابَاتٌ لاَ شَكَّ فِيهِنَّ دَعْوَةُ الْوَالِدِ وَدَعْوَةُ الْمُسَافِرِ وَدَعْوَةُ الْمَظْلُومِ " .
