Massa Ranghar, also called Musalul Khan, was the choudhary of Mandiala. In 1738, Qazi Abdul Razak was killed in an encounter with the Sikhs. The Governor of Lahore, Zakariya Khan Bahadur, appointed Massa Ranghar as the commandant of Amritsar. He used the precincts of the Golden Temple for amusement with dancing girls.
The news of this sacriligeous use of the temple spread to the remote areas. Two Sikhs, Sukha Singh and Mehtab Singh Bhangu, decided to kill Massa Ranghar. They disguised themselves as tax collectors, entered the temple and beheaded Massa Rangar while he was enjoying the dance.
