It is narrated from Sayyiduna Buraydah (may Allah be pleased with him) that when Sayyiduna Ja'far bin Abi Talib (may Allah be pleased with him) returned from Abyssinia, the Messenger of Allah (peace and blessings be upon him) asked him: "What is the most amazing thing you saw there?" He said: I saw a woman carrying a basket of food on her head. A horseman passed by galloping and knocked the basket down, scattering the food. She sat down to gather it, then turned towards that rider and said: "Woe to you on the day when the King (the True King) sets down His Kursi (Footstool) and takes the right of the oppressed from the oppressor." So the Messenger of Allah (peace and blessings be upon him), affirming her words, said: "That nation is not purified," or he said: "How will that nation be purified whose weak member cannot take his right from its strong one without suffering any harm or hardship?"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ata bin al-Sa'ib except Mansur bin Abi al-Aswad and Amr bin Abi Qays."
