Knowledge

Ali is respected not only as a warrior and leader, but as a writer and religious authority. Numerous range of disciplines from theology and exegesis to calligraphy and numerology, from law and mysticism to Arabic grammar and Rhetoric regarded as having been first adumbrated by Ali. According to Hadith which is narrated by Shia and Sufis, Muhammad told about him "I'm the city of knowledge and Ali is its gate..." Muslims regard Ali as a major authority on Islam. Ali himself gives this testimony:

Not a single verse of the Quran descended upon (was revealed to) the Messenger of God which he did not proceed to dictate to me and make me recite. I would write it with my own hand, and he would instruct me as to its tafsir (the literal explanation) and the ta'wil (the spiritual exegesis), the nasikh (the verse which abrogates) and the mansukh (the abrogated verse), the muhkam and the mutashabih (the fixed and the ambiguous), the particular and the general...

According to Seyyed Hossein Nasr, Ali is credited with having established Islamic theology and his quotations contain the first rational proofs among Muslims of the Unity of God. Ibn Abi al-Hadid has quoted

As for theosophy and dealing with matters of divinity, it was not an Arab art. Nothing of the sort had been circulated among their distinguished figures or those of lower ranks. This art was the exclusive preserve of Greece whose sages were its only expounders. The first one among Arabs to deal with it was Ali.

In later Islamic philosophy, especially in the teachings of Mulla Sadra and his followers, like Allameh Tabatabaei, Ali's sayings and sermons were increasingly regarded as central sources of metaphysical knowledge, or divine philosophy. Members of Sadra's school regard Ali as the supreme metaphysician of Islam.; According to Henry Corbin, the Nahj al-Balagha may be regarded as one of the most important sources of doctrines professed by Shia thinkers especially after 1500AD. Its influence can be sensed in the logical co-ordination of terms, the deduction of correct conclusions, and the creation of certain technical terms in Arabic which entered the literary and philosophical language independently of the translation into Arabic of Greek texts.

Ali was also a great scholar of Arabic literature and pioneered in the field of Arabic grammar and rhetoric. Numerous short sayings of Ali have become part of general Islamic culture and are quoted as aphorisms and proverbs in daily life. They have also become the basis of literary works or have been integrated into poetic verse in many languages. Already in the 8th century, literary authorities such as 'Abd al-Hamid ibn Yahya al-'Amiri pointed to the unparalleled eloquence of Ali's sermons and sayings, as did al-Jahiz in the following century. Even staffs in the Divan of Umayyad recited Ali's sermons to improve their eloquence. Of course, Peak of Eloquence (Nahj al-Balagha) is an extract of Ali's quotations from a literal viewpoint as its compiler mentioned in the preface. While there are many other quotations, prayers (Du'as), sermons and letters in other literal, historic and religious books.

In addition, some hidden or occult sciences such as jafr, Islamic numerology, the science of the symbolic significance of the letters of the Arabic alphabet, are said to have been established by Ali through his having studied the texts of al-Jafr and al-Jamia.
