Abu Uthman al-Sabuni

Al-Sabuni, Ismail bin Abdal-Rahman bin Ahmad bin Ismail bin Ibrahim bin Amir, Abu Uthman al-Sabuni al-Shafi'i (Arabic: أبو عثمان الصابوني) also known as Abu Uthman al-Sabuni (373 - 449 AH / 983 - 1057 CE), was a Sunni scholar known for being the leading hadith expert in Khorasan, a jurist of great authority particularly in the Shafi'i school, a Qur'anic exegete, theologian, preacher, and orator. The Sunnis of his time called him the Shaykh al-Islām, and when they used this word they did not mean anyone else. He was eloquent in dialect, broad in knowledge, and was fluent in both Persian and Arabic. Al-Bayhaqi said: "He was the true Imam of the Muslims and the real Shaykh of Islam."
