The Sahaba Memorized the Entire Kawan in the Lifetime of the Prophet's Laisalaim

Many of the Sahaba memorized large portions and then in the years to follow through being around each other, they memorized the rest. He was one of the few people who memorized the entire kawan in the lifetime of the Prophet's la'alaah al-A'alaahAl-A'alaim and mastered all of the Islamic sciences. So this is truly the example of a person who hears knowledge, who memorizes it, and then who practices it in a way that's exemplary for everyone that is around him.
