Khawaja Ghulam Hassan Sewag Shareef was born in a village called Dagar Sewag, District Layyah in the middle of 19th Century. He was raised as an orphan and studied with Moulana Nur Khan, who was a deputy of Khawaja Muhammad Usman Damani (d.1314 AH). By the advice of his teacher, he first took allegiance in the Naqshbandi Path with Khawaja Damani. He established a sufi khānqāh in Hasanabad Thal, near Karor Lal Esan, and was famous for converting large numbers of Hindus in Islam who would convert only by looking at his blessed face. He died on 13 Jamadi-ul-Awwal 1358 AH (1939). His annual Urs is celebrated at his shrine in the form of a purely religious and spiritual congregation.
