Pir Shams Sabzwari Multani, Pir Shahabuddin and Pir Sadardin also wrote Sindhi poetry, and some verses by Baba Farid Ganj Shakar were written in Sindhi. Pir Sadruddin (1290–1409 AD) was another major Sufi Sindhi poet, composing verse in Sindhi's Lari and Katchi dialects. He also wrote in Punjabi, Seraiki, Hindi, and Gujarati. Sadruddin modified the language's old script, which was commonly used by the lohana caste of Sindh Hindus who embraced Islam as a result of his teaching; he called them Khuwajas or Khojas.
