Adi ibn Hatim al-Tai (Arabic: عدي بن حاتم الطائي, romanized: ʿAdī ibn Ḥātim al-Ṭāʾī) was a leader of the Arab tribe of Tayy, and one of the companions of Muhammad.
[3] Adiyy inherited the domain of his father and was confirmed in the position by the Tayy people.
[citation needed] Adi said that before being preached to by Muhammad he practiced Rakusiyya,[4] a syncretic sect which adhered to teachings of both Christianity and Judaism,[4] or a syncretic mixture of Christianity and Sabian religion.
[5] Clément Huart has theorized this sect was linked to Manichaeism due to its syncretic nature.
[citation needed] Bukhari, Muslim, Ahmad ibn Hanbal, and others[9] have attributed hadiths to him.
