azrat Bahauddin Zakariya was a Sufi of Suhrawardiyya order (tariqa). His Moseleum or shrine is situated in the heart of Multan city of Pakiatan province Punjab. His full name was Al-Sheikh Al-Kabir Sheikh-ul-Islam Baha-ud-Din Abu Muhammad Zakaria Al-Qureshi Al-Asadi Al Hashmi.
Sheikh Baha-ud-Din Zakariya known as Bahawal Haq was born at Kot Kehror, a town of Layyah District near Multan, Punjab, Pakistan, around 1170.
His grand father Shah Kamaluddin Ali Shah Qureshi al Hashmi arrived Multan from Makkah en route to Khwarizm where he stayed for a short while. He was from the descendents of Asad Ibn Hashim the maternal grandfather of Hadhrat Ali ibn Abi Talib RA.
In Tariqat he was the disciple of Renowned Sufi Master Shaikh Shahab al-Din Suhrawardi who awarded him Khilafat only after 17 days of stay at his Khanqaah in Baghdaad. For fifteen years he went from place to place to preach Islam and after his wanderings Bahawal Haq settled in Multan in 1222. Baha-ud-din Zakariya died in 1267 and his mausoleum, Darbar Hazrat Baha-ud-din Zakariya, is located at Multan. The mausoleum is a square of 51 ft 9 in (15.77 m), measured internally. Above this is an octagon, about half the height of the square, which is surmounted by a hemispherical dome. The mausoleum was almost completely ruined during the siege of 1848 by the British, but was soon afterward restored by the Muslims
