Nahj al-Balagha
Moreover, Ibn Abi al-Hadid, in confirmation of Nahj al-balagha's documents also mentions in the book of "Sharh Nahj al-Balagha" that it is a wrong word which is claimed by someones who assume that the major sermons of Nahj al-Balagha are not Ali's words, whereas this is actually Ali's speeches; and he presents his arguments to prove that. Besides, Sheikh Muhammad Abdah (the Egyptian Mufti) confirms that Nahj al-Balagha is the words of Ali.
