Ahmad ibn Umar ibn Alī, known as Nizamī-i Arūzī-i Samarqandī (Persian: نظامی عروضی) and also Arudi ("The Prosodist"), was a poet and prose writer who flourished between 1110 and 1161. He is particularly famous for his Chahar Maqala ("Four Discourses"), his only work to fully survive. While living in Samarqand, Abu’l-Rajaʾ Ahmad b. ʿAbd-Al-Ṣamad, a dehqan in Transoxiana, told Nezami of how the poet Rudaki was given compensation for his poem extolling the virtues of Samanid Amir Nasr b. Ahmad. Source: Wikipedia (en)
