Bu Ali Qalandar awarded Sheikh Usman with the title of Shahbaz, which became the part of his name. Since he was used to wear red dress, so he is called Lal Shahbaz.
Syed Usman Marvandi (1177 – 1274), popularly known as Lal Shahbaz Qalandar (Sindhi: لعل شھباز قلندر), was a Sufi saint and religious-poet of present-day Pakistan and Afghanistan. He is highly regarded and respected by both Muslims and Hindus because he preached religious tolerance between the faiths. He was called Lal ("ruby-colored") after his usual red attire and "Shahbaz" to denote a noble and divine spirit and "Qalandar" as he was a wandering holy man. The spiritual song "Dama Dam Mast Qalandar" glorifies Lal Shahbaz Qalandar's teachings, and the song is widely used in Pakistan, India, Afghanistan and Bangladesh. Originally written in the 13th century, the song has been sung by various singer since then, and is widely popular in the sub-continent
Lal Shahbaz Qalandar, son of Ibrahim Kabeeruddin, was born in Maiwand, today's Afghanistan. His ancestors had migrated from Baghdad, Iraq and settled in Mashhad, Iran before moving to Maiwand. He lived when the Ghaznavid and Ghurids ruled in the Indus region(today's Punjab, Pakistan).
A contemporary of Rumi, he travelled around the Muslim world and settled in Sehwan, Sindh where he was eventually buried. There is evidence of his presence in Sindh in 1196 when he met Pir Haji Ismail Panhwar of Paat and he is believed to have arrived in Sehwan around 1251. There he established a meeting house (khanqah), taught in the Fuqhai Islam Madarrsah and wrote his treatises Mizan-us-Surf, Kism-e-Doyum, Aqd and Zubdah. Lal Shahbaz lived a celibate life.
In Multan, he met Baha-ud-din Zakariya of the Suhrawardiyya order, Baba Fariduddin Ganjshakar of the Chishtiyya and Syed Jalaluddin Bukhari. The friendship of these four became legendary, they were known as the Chahar Yar (In Persian "the four friends"). According to some historians, the four friends visited various parts of Sindh, Punjab (in present-day Pakistan) and southern part of India.
Shahbaz became a profound scholar of religions, fluent in many languages including Pashto, Persian, Turkish, Arabic, Sindhi and Sanskrit. This was also the time period when Ghiyas ud din Balban (reigned: 1266 – 1287) ruled India.
Following his death, Hindus within Sindh began to identify Lal Shahbaz Qalandar as an incarnation of their patron deity, Jhulelal. This connection was emphasized by the popular spiritual song Dama Dam Mast Qalandar which referred to him by the name Jhulelal. Over time, the Jhulelal has become a nickname for him, among both Hindu and Muslim Sindhis
