Allah warns you to be aware and be careful of the supplication of the one you oppressed!
A true story which took place in Baghdad, it was narrated about Ibn Furaat Al Abbasi.
An old lady, she had a garden next to a minister, this minister’s name was Ibn Furaat. Ibn Furaat confiscated the lady’s garden, he was a minister, he confiscated her garden so she went to him and said, this is my garden that you have confiscated. I have no brother or father to help me, I depend on my garden!
Ibn Furaat replied, the garden is mine – just go away!
She said to him, I swear by Allah I’m going to make duah against you.
The minister responded and told her, go and make duah at the last third part of the night! He was mocking her!
There was a scholar there who heard the conversation, he started shaking when he heard Ibn Furaat say that, because that’s not an easy matter, it’s not easy to say. This is very serious.
Ibn Furaat is not worried, he’s mocking Allah!!
The lady told him, may Allah reward you good and then she left.
The lady went away, a whole month she was making duah, the whole month she was making duah against him! Then one day Ibn Furaat did something wrong, the Khalifa was not pleased with him and he ordered for one of his hands to be cut off one week and his neck the following week.
One day she passed by him when he was awaiting his execution. She told him, may Allah reward you good, you guided me to the right way.
Ibn Furaat was shocked, he asked her, why are you telling me this here?
The lady said, you directed me to make duah at the last third part of the night.
The following week Ibn Furaat’s head was decapitated.
Allah answers the oppressed and persecuted – there is nothing between them and Allah. Duah is effective, make a lot of duah and remain patient. Indeed the fruits of duah are the sweetest!
There’s a hadith which mentions the power of the supplication of the oppressed. Allah swore by His honor and grandeur, He said by My honor, grandeur and majesty I will grant you a victory even if it’s after a while! This is hadith.
In another hadith it states that the supplication of the oppressed – there is no barricade, no veil between the supplication of the oppressed and Allah!
