Baha-ud-din Zakariya (1170-1267), also spelled as Bahauddin Zakariya, and also known as Baha-ul-Haq and Hazrat Bahauddin Zakariya Multani (Rahmatullah Alaih), was a Sufi of Suhrawardiyya order (tariqa). His full name was Abu Muhammad Bahauddin Zakariya. He was from the lineage of Hadhrat Asad Ibn Hashim hence Hashmi.
Sheikh Baha-ud-Din Zakariya was born at Kot Kehror (Karor Lal Esan), a town of the Layyah District near Multan, Punjab, Pakistan, around 1170. His grandfather Shah Kamaluddin Ali Shah Qureshi arrived in Multan from Mecca en route to Khwarezm where he stayed for a short while.
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 Khanqah in Baghdad. For fifteen years, he travelled to different cities in order to preach Islam and finally settled in Multan in 1222.
