Abu Hurairah (Radiallaho Anho) reports, Rasulullah (Sallallaho Alaihi Wassallam) said:
"There are three persons whose Prayer [Dua] is not rejected,
The fasting person until he breaks the fast,
the just ruler
and the oppressed person,
whose Dua Allah (Subhanahu wa Taala) lifts above the clouds and opens unto it the doors of Jannah and Allah (Subhanahu wa Taala) says,
'I swear by my honor, verily , I shall assist you, even though it may be after sometime.' "
{ Tirmidhi, Ibn Hibban }
