Sayyida Nosrat Beygum Amin was one of the most outstanding female jurisprudents and theologians of the 20th century. After being given the permission of ijtihad by prominent scholars, thus entitled mujtahida, she in turn granted permission of ijtihad to future renowned female and male scholars, one of them being the grand Ayatollah Mar’ashi Najafi. This paper offers a brief account of Lady Amin’s academic and spiritual standing, along with her lineage, teachers, and works. Her ardent love for God led her to fervently study in a variety of Islamic disciplines, leading her to moral excellence and reaching the level of ijtihad. In addition to her academic scholarship, Lady Amin displayed firmness in her movement against the emergence of modernism and false propaganda against Islam when she rose against the misleading ideologies promoted by Reza Khan. In a generation bombarded with celebrities that entice today’s youth to overlook true exemplars, Lady Amin is an example of a woman with notable achievements in which people can apply to their modern lives.
