Nahj al-balaghah comprises various issues that cover major problems of metaphysics, theology, fiqh, tafsir, hadith, prophetology, imamate, ethics,social philosophy, history, politics, administration, civics, science, rhetoric, poetry, literature, etc. Most of the discussions about various theological issues and philosophical notions in Islam have their origin in this very book. Similarly, all the controversies regarding socio-political problems in the Muslim society and state left their echo in Nahj al-balaghah,or rather those were inspired from the utterances of al-lmam 'Ali (as).
The book not only reflects the spirit of early Islam and the teachings of the Quran and the Prophet (saw) in the proper perspective, but also serves as a guide to traverse the future in the light of these teachings.
It is a matter of regret that Nahj al-balaghah was not properly utilized by the Muslims as a source book of Islamic philosophy, kalam, fiqh, and ethics due to misconceptions about its attribution to al-Imam'Ali (as) In the presence of strong and sufficient evidence in support of the contents of the book being authentic, it was sheer prejudice and lack of the spirit of inquiry that was responsible for neglecting such a reliable source of Islamic ideas.
In recent times, the Orientalists have spread the unfounded doubts of Ibn Khallikan and al-Dhahabi among Muslim and non-Muslim scholars in the name of objectivity in research, thus giving a respectable appearance to their ignorance, which was, of course, combined and prompted by their motive to ali enate the Muslims from their intellectual heritage. I know many a scholar in India and Pakistan questioning the authenticity of Nahj al-balaghah's ascription to
Amir al-Mu'minin using lofty words of research-objectivity with a hefty-pose of a dispassionate seeker of truth. None of them, I am sure, ever studied any book about early sources of the sermons and letters of al-'Imam 'Ali (as), nor did any one of them ever try to gain really objective information about the book. Unfortunately none of them bothered to go through even the valuable research done by Imtiyaz 'Ali Khan 'Arshi, a widely read and respected writer in the literary circles of Urdu in the Subcontinent.
It was because of my first-hand knowledge of this pitiable situation that I have intentionally devoted the major part of the present article to the issue of the authenticity of the attribution of the contents of Nahj al-Balaghah, in the light of earlier sources, to 'Ali (as).
Those who insist upon denying the veracity of Nahj al-balaghah are either suffering from a malady of deep-rooted prejudice spread through the propaganda of the supporters of Banu Umayyah, or their minds and spirits have been blinded by the propagation of falsehood by the Orientalists under the garb of high-sounding academic jargon. If our minds are cured of this jaundiced perception of our own past, Nahj al-balagha can be paid the attention it deserves and its contents will be studied and its meanings will be fully explored and exploited for a better understanding of Islamic ideas and realities.
A look at the subjects discussed in Nahj al-balagha will be helpful in ascertaining the wide scope of this invaluable treasure of wisdom. So far a few attempts to classify the subject matter of the book have been made none of which has been comprehensive. A subject-wise index of the contents of Nahj al-balaghah has been prepared by 'Ali Ansariyan and published in Arabic under the title al-Dallil 'ala mawdu'at Nahj al-balaghah in 1395/1975. It was translated and published three years ago in Persian with the sub-title Nahj al-balaghah mawdu'i.
