Concept:Hilf al-Fudul was a pact formed in Makkah to defend justice and protect the weak.
Explanation:The alliance of Fudul was established by noble-minded Quraysh leaders after a visiting trader was wronged by an influential citizen.
Its members assembled at the house of Abdullah ibn Jud’an and pledged to stand with the oppressed against the oppressor, regardless of tribe or social status.
This pact was important because it gave practical protection to the weak and ensured that the wronged could claim their rights.
It did not distribute Zakat, because Zakat was made obligatory only in Madinah after the Hijrah.
Nor was its aim to defend the Ka’bah from invaders or to draw membership from outside Makkah.
Its purpose was to protect the interests of people who were treated unfairly by powerful clans.
Answer:D. Protected the interest of the oppressed
