âÂÂIzz al-Dën âÂÂAbu Hamëd âÂÂAbd al-Hamëd bin Hëbat-Allah ibn Abi al-Hadëd al Mutazilë al-Mada'ini (), also known as Ibn abi'l-Hadid (30 December 1190 â June 1258; 586âÂÂ656 AH), was a Mutazili Shafi'i scholar and writer during the Middle Ages. He studied under Abu'l-Khayr Musaddiq ibn Shabib al-Wasiti (died AD 1208/605 AH) and is best known for his commentary on the Nahj al-Balagha, which he titled Sharh Nahj al-Balagha.
Ibn Abi'l-Hadid was born on Sunday, 1st Zulhijja, 586 AH/ 30 December 1190 AD in the city of al-Mada'in, now Salman Pak, Baghdad Governorate, Iraq.
Regarding the fabrications of Hadiths, he said that lies had been introduced into the hadith collections of Shias in order to favour their Imam, Ali, or due to their enmity with other religious groups. Regarding the early Caliphate, Al-Hadid explains Ali's position during the early Caliphates in his commentary in his Sharh Nahjul Balagha. According to him Ali did not approve of the Rashidun Caliphate and did not follow them in prayers. He further states that he follows the example of Ali and does not go beyond that, going as far as to curse Muaawiyah.
