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)
عَنِ النَّبِيِّ ﷺ قَالَ ثَلَاثُ دَعَوَاتٍ لَا شَكَّفِيهِنَّ دَعْوَةُ الْمُسَافِرِ وَالْمَظْلُومِ وَدَعْوَةُ الْوَالِدِ عَلَى وَلَدِهِ
