Ma'mar ibn al-Muthanna (728–825) also known as Abu Ubayda (Arabic: أبو عبيدة) was an early Muslim scholar of Arabic philology. He was a controversial figure; later scholar Ibn Qutayba remarked that Abu Ubayda "hated Arabs," though his contemporaries still considered him perhaps the most well-rounded scholar of his age. Whether or not Abu Ubayda was truly a supporter of the Shu'ubiyya is a matter of debate. Source: Wikipedia (en)
