Zaydulillahu Ta'ala Anhuma

Abdullah ibn Abbas al-Dulillahu Anhuma would go on to become known as Habrul Ummah, the scholar of the Ummah. His greatest teacher after the Prophet SallAllahu Alaihi Wasallam of course is Zaydul Nafabat. Now it's very rare to find a person as well that all of the Sahaba gathered around this way and considered a scholar.
