á¹¢alÃÂḥ al-Dën al-Malik al-NÃÂá¹£ir Aḥmad ibn IsmÃÂÿël (died 1424), numbered al-NÃÂá¹£ir Aḥmad I, was the eighth Rasà «lid sultan of Yemen from 1400 until his death. He succeeded his father, al-Ashraf IsmÃÂÿël I, and was succeeded by his son, al-Maná¹£à «r ÿAbdallÃÂh.
Al-NÃÂá¹£ir Aḥmad was the last successful Rasà «lid, attaining military victories in Yemen and receiving diplomatic gifts from China. The Chinese admiral Zheng He visited Aden during his fifth, sixth and seventh voyages. On the first of these, according to the anonymous TÃÂrikh al-dawla al-Rasà «liyya fë l-Yaman, an envoy from the fleet proceeded overland to meet al-NÃÂá¹£ir in in March 1419, bringing with him gifts of porcelain, musk, storax and silk woven with gold.
After al-NÃÂá¹£ir's death, the dynasty declined rapidly, losing all power in 1454.
