Ali al-Uraidhi ibn Ja'far al-Sadiq

Ali al-Uraydi ibn Ja'far al-Sadiq, simply known as Ali al-Uraydi, was a Muslim scholar and the son of Ja'far al-Sadiq, the sixth Shia Imam for Twelvers and Ismailis. Thus he was the brother of Isma'il, Abdullah al-Aftah, Muhammad Al-Dibaj and Musa al-Kazim. He was known by the title al-Uraydi, because he lived in an area called Urayd, about 4 miles from Medina. He was also known by the nickname Abu al-Hasan. In Shia tradition by Shaykh Tusi, he was a close companion of his brother Musa al-Kazim, from whom he narrated hadith, and was reportedly a companion of Ali al-Rida (799–819) and Muhammad al-Jawad (819–835), and also met Ali al-Hadi (835–868) while he was young.
