A few hundred metres east of the Shah Rukn-e-Alam mausoleum stands the older and slightly less spectacular Shrine of Bahauddin Zakariya — the saint who founded the Suhrawardiyya order in Multan in the 1220s and gave the city its character as a centre of Sufism. He is known throughout southern Punjab and Sindh as Bahawal Haq ("the ornament of the Faith"), and his name is invoked for safety by farmers, boatmen and shepherds across the region.
The tomb is a square brick structure with a hemispherical dome, less ornate than its grandson's but with the same family of Multani blue, turquoise and white tilework. It was badly damaged in the 1848 siege when the powder magazine of the British besiegers exploded inside the fort and largely rebuilt afterwards. The complex includes a working mosque, an active langar (free kitchen) and a guesthouse for pilgrims, and is at its busiest during the saint's urs in November.
