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. (Using translation from Abū Dāʾūd 1536)
أَنَّ نَبِيَّ اللهِ ﷺ كَانَ يَقُولُ ثَلَاثُ دَعَوَاتٍ مُسْتَجَابَاتٌ لَهُنَّ لَا شَكَّ فِيهِنَّ دَعْوَةُ الْمَظْلُومِ وَدَعْوَةُ الْمُسَافِرِ وَدَعْوَةُ الْوَالِدِ عَلَى وَلَدِهِ
