Uthman ibn Sa'id al-Darimi

Uthman ibn Sa'id al-Darimi (Arabic:عثمان بن سعيد الدارمي), full name Abu Sa'eed Uthman ibn Sa'id ibn Khalid ibn Sa'id al-Darimi, was a 9th-century Islamic scholar and Athari  theologian. A narrator of hadith, he was known for being extremely strict against the Jahmi and Karami schools of thought which prevailed during his time. His best known work is the Naqd 'Uthman ibn Sa'id 'alal-Marisi al-Jahmi al-Anid, a detailed refutation against one of his contemporaries, Bishr al-Marisi.

Biography
Uthman ibn Sa'id al-Darimi was born in the year 815. He adhered to the Shafi'i school of thought. Darimi learned hadith and other prophetic traditions from the leading scholars of his time, Ali ibn al-Madini, Yahya ibn Ma'in and the founder of the Hanbali school, Ahmad ibn Hanbal. He became a narrator of hadith, and later scholars like Ibn Hibban and Hakim al-Nishapuri would narrate hadith from him.

Uthman ibn Sa'id al-Darimi died in the year 894.

Controversy
Uthman ibn Sa'id al-Darimi was known for his aggression against the Jahmi school. He was severe against Bishr al-Marisi, even going as far as to excommunicate him and write a book of refutations against him. His writings were quoted by later traditionist Athari scholars like Ibn Taymiyyah.

Aside from the Jahmis, Darimi was also against the Karami school. He stood against them, denouncing them repeatedly for their anthropomorphistic beliefs regarding God's nature. His persistent efforts to defame the Karamiyyah resulted in their founder, Ibn Karram, being expelled from Nishapur.

The historian Al-Dhahabi said that Darimi was a “stinger in the eyes of the heretics.”
