Can you provide the reference for this:
Nabi (sallallahu ‘alayhi wa sallam) said: “Three prayers (supplications) are not rejected, there is no doubt in this; The du’a of a father, the du’a of a traveller and the du’a of an oppressed person”
Imams Abu Dawud and Ibn Majah (rahimahumallah) have recorded this Hadith on the authority of Sayyiduna Abu Hurayrah (radiyallahu ‘anhu).
(Sunan Abi Dawud, Hadith: 1531, Sunan Ibn Majah, Hadith: 3862)
Imam Tirmidhi (rahimahullah) has recorded the narration with slight variation in the wording.
(Sunan Tirmidhi, Hadith: 1905, 3448)
And Allah Ta’ala Knows best.
