'Ali ('a) says...
'Ali ('a) says: When He decrees the creation of a thing, He says to it, "Be", and it assumes existence; but not through an audible voice which strikes the ear or a cry that can be heard. Indeed the speech of God, glory be to Him, is but His created Act, which did not exist before [it came into existence]. Had it (Divine speech) been itself eternal, it would be another god besides Him.
(Sermon 186) In addition, there are other musnad traditions on this subject related from 'Ali ('a), only some of which have been collected in the Nahj al-balaghah, and can be traced back to his time. On this basis, there is no room for doubting their genuineness. If any superficial resemblance is observed between the statements made by 'Ali ('a) and some views held by the Mu'tazilah, the probability to be allowed in this connection is that some of his ideas were adopted by the Mu'tazilah.
The controversies of the Muslim theologians (mutakallimun), both the Shi'ah and the Sunni, the Asha'irah as well as the Mu'tazilah, generally revolved around the doctrine of rational basis of ethical judgement concerning good and evil (al-husn wa al-qubh al-'aqliyyan).
This doctrine which is not other than a practical principle operating in human society, is considered by the mutakallimun to be also applicable to the Divine sphere and govern the laws of creation; but we find no trace of it in the Nahj al-balaghah, similarly there is no sign of it in the Quran. Had the ideas and beliefs of the mutakallimun found their way into the Nahj al-balaghah, first of all the traces of this doctrine should have been found in that book.
The Nahj al-balaghah and Philosophical Concepts Some others, on coming across certain words such as 'existence' (wujud), 'non-existence' ('adam), 'temporality' (huduth) and 'pre-eternity' (qidam), and so on in the Nahj al-balaghah, have been led to assume that these terms entered the Muslim intellectual world under the influence of Greek philosophy and were inserted, unintentionally or intentionally, into the discourses of 'Ali ('a).
If those who advocate this view had gone deeper into the meanings of these words, they would not have paid heed to such a hypothesis. The method and approach adopted in the arguments of the Nahj al-balaghah is completely different from that of the philosophers who lived before al-Sayyid al- Radi or during his time, or even those born many centuries after the compilation of the Nahj al-balalghah .
