The title, according to the people of knowledge is the name by which a person is known, indicating either his praise or slander. And because Aba al-Fadl al-Abbas son of the Commander of the Faithful (peace be upon both of them) had all good qualities, morals and virtues, all his titles were signs of his praise, reverence and magnificence, as he (peace be upon him) is the son of the Commander of the Faithful; Ali Ibn Abi Taleb (peace be upon both of them) and the brother of the two Imams the beloved grandsons of the Great Prophet (Allah's prayers be upon him and upon his holy Household) and the masters of the youth of Paradise; al-Hassan and al-Hussayn (peace be upon both of them).
And in addition to his noble status, he is the descendant of the people of the House of the Revelation and Prophethood, and the one educated by those who were raised by the Great Messenger of Allah (Allah's prayers be upon him and upon his holy Household), knowing that the Holy Prophet has said: "My Lord has educated me and [gave me] the most beautiful education."
