‘Izz al-Dīn ‘Abu Hamīd ‘Abd al-Hamīd bin Hībat-Allah ibn Abi al-Hadīd al Mutazilī al-Mada'ini[1][2][3] (Arabic: أبو حامد عز الدین عبدالحمید بن أبي الحُسین ھبة الله بن محمد بن محمد بن الحُسین بن أبي الحَدِید المَدائني المعتزلي), also known as Ibn abi'l-Hadid (30 December 1190 – June 1258; 586–656 AH), was a Mutazili[4][5][6] Shafi'i[7] scholar and writer during the Middle Ages.
He studied under Abu'l-Khayr Musaddiq ibn Shabib al-Wasiti (died AD 1208/605 AH)[8] 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.
According to him Ali did not approve of the Rashidun Caliphate and did not follow them in prayers.
