Ismāʿīl ibn Ibrāhīm al-Juzajānī

Al-Nasāʾī, of Persian origin, was born in 830 CE in Nasa, Khorasan (present-day Turkmenistan). He was a prolific hadith scholar who travelled extensively across the Arabian Peninsula and settled in Egypt, where he taught and narrated hadith. He authored the important hadith collections As-Sunan al-Kubra and its abridged version Sunan al-Sughra, which are among the six canonical Sunni hadith books. Known for his piety and asceticism, he fasted regularly and was respected for his knowledge. Near the end of his life, while in Damascus, he was martyred in 915 CE after a controversial lecture praising Ali, which angered the local anti-Alid crowd. His death marked the loss of a major figure in early Islamic scholarship.
