[ALLAH’S Quran – 27:62] “Who responds to the oppressed when he calls out to Him, and relieves his suffering and who will make you inheritors of the earth? Then, is there a god besides God? How little you pay heed!”

The Prophet (Peace Be Upon Him) has said:
[Bukhari, Book #43, Hadith #628] “Narrated Ibn ‘Abbas: The Prophet sent Mu’adh to Yemen and said, “Be afraid, from the curse of the oppressed as there is no screen between his invocation and Allah.”

[Muslim, Book #001, Hadith #0027] “It is reported on the authority of Ibn ‘Abbas that Mu’adh said: The Messenger of Allah sent me (as a governor of Yemen) and (at the time of departure) instructed me thus:……………………………..Beware of the supplication of the oppressed for there is no barrier between him and Allah.”
