Ibn Khallikan
On the other hand, as with the majority of posthumous works of Shia theology that emerged centuries after the life of Prophet Muhammad, Sunni scholars do not regard the Nahj al-Balagha as authentic. According to one Shi‘i source, the first person to raise doubts about its attribution to Ali was Ibn Khallikan, a Sunni scholar (d. 1211/1282). Izz al-Din ibn Hibatullah ibn Abi l-Hadid's (d. 656/1258) commentary and collection, "Sharh Nahj al-Balagha", is widely disseminated.
