This famous song is in honour of Hazrat Lal Shahbaz Qalandar (1177--1274) who was born in Marwand (Afghanistan) as Syed Shah Hussain Marwandi. A contemporary of Rumi, he settled in Serwan or Sehwan (currently in Sindh, Pakistan) where his shrine is still worshipped. He preached religious tolerance between Hindus and Muslims. He was fluent in many languages including Sindhi and Sanskrit. Hindus regarded him as the incarnation of Bhrithari. He was called Laal (red) after his red attire, Shahbaz (noble falcon) due to his noble spirit, and Qalandar for his Sufi orientations.
