Saadir Adaasi Sahib was an Indian Sufi imam at the court of the Mughal emperor Akbar during the 16th century. He opposed Akbar's toleration of Hinduism (including his wife Mariam-uz-Zamani's own Hindu faith) and his lifting of the jizya tax, driving him to support his brother-in-law Sharifuddin Hussain's rebellion in 1564.
