Manka
From Wikipedia, the free encyclopedia
Outside the Delhi Gate, nearly twelve yards (351/2 feet to be exact) in length, there is a stone of chocolate color with marks of light yellow on it, 27 inches in diameter and 78 inches thick, with a hole through the middle 9 inches in diameter. It is called Manka. People say the saint wore it round his neck, while some maintain that it was his thumb ring. The tomb is asserted to be 1300 years old. It is possible that it may belong to the times of the early Muslim invasion under Mohammad -bin-Qasim.
