Ibn `Abbaas, may Allah be pleased with him, was similar to Ibn Az-Zubayr, may Allah be pleased with him, in that both experienced the Prophetic era while still children. The Prophet died before Ibn `Abbaas, may Allah be pleased with him, had reached manhood. He had also been granted, while still very young, all the basic materials of manliness and the principles of life by the Prophet who liked him most, praised him, and taught him pure wisdom.
Due to his firm belief, gentleness, good character, and the richness of his knowledge, he was able to occupy a very high rank among the men around the Prophet .
He was the son of Al-'Abbaas Ibn `Abdul-Muttalib Ibn Haashim, the Prophet's uncle. His epithet was "The Nation's Scholar". He deserved the title and position due to his vast knowledge, the enlightenment of his mind, and his versatility.
Ibn `Abbaas, may Allah be pleased with him, came to knowledge at a very early age, a knowledge which increased as days went by. That is because the Prophet was always drawing `Abdullaah close to him, patting his shoulders and asking Allah, "O Allah, bless him with the full knowledge of the religion and interpretation of the Holy Qur'aan." The Prophet repeated the same prayer for his cousin `Abdullaah in various situations. In this way `Abdullaah Ibn `Abbaas, may Allah be pleased with him, realized that he had been created to acquire knowledge, and his intellectual capabilities inclined strongly in that direction. Although his age did not exceed 13 when the Prophet died, he had not spent his childhood in vain. He had attended the Prophet's assemblies and learned his words by heart.
When the Prophet died, he was eager to learn from the Companions, may Allah be pleased with them, what he had failed to hear or learn from the Prophet himself.
He turned into a continuous question mark. Whenever he heard that someone had acquired wisdom or learned a Hadeeth by heart, he hurried to learn it from him. His bright ambitious mind forced him to examine all that came to his ears.
He was not just concerned with gathering information, but with examining it and its sources. He once said about himself, "If I wanted to know something about an issue I would ask 30 Companions."
He drew a picture demonstrating his concern to reach truth and knowledge: When the Prophet died, I said to one of the Ansaar youth, "Let's go to the Prophet's Companions to ask them, as they are still numerous." He said, "O Ibn `Abbaas, how strange you really are! Do you think that people are in need of you while the great Companions are still among them?" The young man dropped the matter, whereas I turned to ask the Prophet's Companions. Whenever I was informed that someone had related a Hadeeth, would go to him in the afternoon while he was napping. I put my gown as a pillow under my head in front of his door. The wind scattered the dust over me. When he finished his nap and came out and saw me, he said, "O Prophet's cousin, what is it that brought you here? Why didn't you send for me?" Then I would say, "No, it's you who deserves to be visited." Then I would ask him about the Hadeeth and learn from him.
In this way our young man went on asking and asking and asking, then examining the answers and discussing them with a curious mind.
Every day his wisdom and knowledge developed until he achieved, while still a youth, the wisdom, patience, and eloquence of the elderly, so much so that the Commander of the Faithful `Umar, may Allah be pleased with him, was eager to consult with him in every great issue. He called him, "The young leader of the elderly". Ibn `Abbaas, may Allah be pleased with him, was once asked, "How could you acquire all that knowledge?"
He answered, "By means of a questioning tongue and a reasoning mind." Through his continuously inquiring tongue, his ever- detecting mind, and, moreover, his humility and gentleness, Ibn `Abbaas, may Allah be pleased with him, was to become the nation's scholar.
Sa'd Ibn Abi Waqqaas, may Allah be pleased with him, described him in the following words: I've never seen one with such presence of mind nor more intellectual and milder than Ibn `Abbaas, may Allah be pleased with him. I've seen `Umar, may Allah be pleased with him, although surrounded by those who attended Badr, inviting him to discuss difficult problems. Whenever lbn `Abbaas, may Allah be pleased with him, spoke out his view point, 'Umar, may Allah be pleased with him, always stuck to it.
'Ubaydallaah Ibn `Utbah once said: I've never seen anyone more knowledgeable in the Prophet's Hadeeth than Ibn `Abbaas, may Allah be pleased with him. Neither did I see anyone more knowledgeable during Abu Bakr, `Umar or `Uthmaan's caliphates than him; or more accurate in what he says in terms of jurisprudence or more knowledgeable in terms of poems, the Arabic language, Quranic interpretation or religious matters. He divided his time, each day teaching one subject or another, jurisprudence, Quranic interpretation, invasions, poems, and history, each one a different day. I've never seen a scholar listening to him without submitting himself completely to him, nor asking without being impressed by his vast and rich knowledge.
Ibn `Abbaas, who was appointed governor of Basra during the caliphate of 'Ali Ibn Abi at- Taalib, may Allah be pleased with him, was once described by a Muslim in the following words: He stuck to three matters, and gave up three. He dazzled men's hearts whenever he talked. He was a good listener whenever he was spoken to. He chose the easiest of two matters whenever he was opposed. He gave up hypocrisy. He gave up the companionship of wicked people. He gave up all that is excusable.
His diverse culture and vast, comprehensive knowledge were admirable. He was the skillful, shrewd authority in every field of knowledge: Quranic interpretation, jurisprudence, history, Arabic language and literature. Therefore, he was a recourse for the seeker after truth. People traveled to him in groups from all parts of the Islamic world in order to listen to him and to learn from him.
