Little is known about Uwais Khagga except that he was a disciple of the famous saint Shaikh Rukn-i 'Alam. His grave is typical of those found around Multan, built in the style exemplified by the tomb of Bahaduun Zakaria. It displays the use of traditional tile-work in both the exterior and interior.
