Núrayn-i-Nayyirayn (Arabic: نورين نيران, meaning "twin shining lights") are two brothers who were followers of Baháʼu'lláh, the founder of the Baháʼí Faith, a global religion of Persian origin. They were beheaded in 1879 as a result of being Baháʼís. Numerous letters and tablets were written in their honour by Baháʼu'lláh, who gave them the titles which they are commonly known as: the King of Martyrs and the Beloved of Martyrs.
