Ismail Samani

Abū Ibrāhīm Ismā'īl ibn-i Aḥmad-i Sāmāni (Persian: ابو ابراهیم اسماعیل بن احمد سامانی; May 849 – 24 November 907), better known simply as Amir Ismail-i Samani (اسماعیل سامانی), and also known as Isma'il ibn-i Ahmad (اسماعیل بن احمد), was the Samanid amir of Transoxiana (892–907) and Khorasan (900–907). His reign saw the emergence of the Samanids as a powerful force. He was the son of Ahmad ibn-i Asad and a descendant of Saman Khuda, the eponymous ancestor of the Samanid dynasty who renounced Zoroastrianism and embraced Islam.
