After the invasion of Nadir Shah and acting on his advice Nawab Zakaria Khan decided to totally exterminate the Sikh community once for all. To achieve this objective, he issued instructions to his officials and to village heads to kill or arrest alive Sikhs, wherever and whenever found. He also announced cash rewards of Rupees ten, fifty and eighty respectively for informers, killers and arresters of the Sikhs. As a result of these orders of Zakaria Khan, the Governor of Lahore (now in Pakistan) thousands of Sikhs, men, women and children were killed and arrested without any rhyme or reason. The notorious village heads and officials who carried out the orders of the Governor to gain his favours were Karma of village Chheena, Rama Randhawa of village Talwandi, Sahib Rai Sandhu of village Naushehra Dhaala, Har Bhagat Niranjania of village Jandiala, Dharam Das Topi of Jodhnagar and village heads of villages Naushehdra Punuan and Majitha. They sent cart loads of heads of Sikhs to Lahore, in addition to thousands arrested and sent to Lahore for execution in a merciless manner publicly in Lahore daily. They even killed women and presented their heads for reward. Massa Ranghar, the village head of Mandially exceeded all limits and behaved in a most hated, mischievous and offensive manner, hurting religious sentiments of Sikhs, after he was handed over charge of Sri Darbar Sahib (Golden Temple), in Amritsar. The premises was captured earlier by the Governement forces. He used parikarma of the premises as stable for horses and main Hall of holy Golden Temple as a Dancing Room. He would seat himself on a beautiful cot (Palang), smoke hukka and watch prostitutes dancing in the main hall of the most sacred place of the Sikh community. Around the building he had posted armed guards to prevent entry of anyone and everyone without permission. Due to persecution in Punjab the Sikhs had moved to hills, Jungles, ravines and deserts. One such group (Jatha) of Sikhs was temporarily camping near Jaipur City in Rajasthan. Some-one communicated to them the sad news of desecration of Harimandir Sahib at Amritsr. The heart rendering account of misdeeds of Mass a hanghar sent shock waves through the hearts of all the sikhs present there. One among them, Bhai Mehtab Singh immediately jumped to his feet and volunteered himself to punish and culprit Massa Rangar forthwith. He announced that he would serve the head of the wretched Massa in Amritsar and bring it back in Jaipur to show the same to all Sikhs present here. Another Sikh named Bhai Sukha Singh volunteered to accompany Mehtab Singh, to help him accomplish the sacred task. Both were granted permission by the Jatha chief and special prayer was held for the success of their mission. Both Bhai Sukha Singh and Bhai Mehtab Singh immediately proceeded towards Amritsar and arrived there in the month of August, 1740. They put on the garbs of village chaudharies and carried with them a bag full of well ground pieces of broken earthen wared and thus it appeared that the bag was full of coins. They straightway headed for Harmandir Sahib. On arriving there, they told the guards who checked their entry into the premises that they were village heads and had come to deposit land revenue with Massa Ranghar. Thus they managed to befool the guards and gained entry to Harimandir Sahib. They tied their horses with a tree near the entrance of the Harimandir Sahib now reveredly known as Lachi Ber and proceeded further. They found Massa Ranghar sitting on his cot fully intoxicated, smoking Hukka and watching dancing prostitutes. The scene enraged them. Bhai Sukha Singh remained near the door of main hall while Bhai Mahtab Singh went inside. He threw the bag under Massa’s cot and said, “ Here is land revenue.” Massa Rangar happily bent down to pick up the bag supposed to be full of coins. Bhai Mehtab Singh drew out his sword swiftly and with its single blow, cut off the head of Massa Rangar.
