Abu ʾl-Ḥasan al-Naḍr ibn Shumayl ibn Kharasha al-Māzinī al-Tamīmī (Arabic: أبو الحسن النضر بن شميل بن خرشة المازني التميمي; 740–819/820) was an Arab scholar and poet from central Asia active in Iraq.
[1] Tradition records that a large number of scholars—700 or even 3,000—went to see him off at the Mirbad in order to persuade him to stay, but when they would not personally guarantee him even an extremely modest living he left.
[1][3] In Marw, al-Naḍr became a qāḍī (judge) and helped establish the sunna (Islamic custom) throughout Khorasan.
[1] According to al-Ṭabarī, he was among the 26 scholars interrogated by Isḥāq ibn Ibrāhīm during al-Maʾmūn's persecution of 833 and one of the 21 sent to Tarsus for refusing to assent to the Muʿtazila doctrine.
His most important work was the five-volume Kitāb al-ṣifāt fi ʾl-lugha, which is summarised in detail in the Fihrist of Ibn al-Nadīm.
