Shaheed Hari Singh was born in the village of Jhabra, located in the Jaisalmer district of Rajasthan, on September 1, 1976. His father, Shri Radhakishan Singh, worked as a farmer in the village. His mother's name is Smt. Jatan Kanwar. From his childhood, he was deeply devoted to cow service and had a compassionate attitude towards wildlife. The family's financial condition was modest. After completing his education up to the 8th grade, he began assisting his father in agricultural work.

Along with the family farming, his daily routine prominently included cow service, environmental protection, and caring for wildlife. In the desert region, where water is extremely scarce, he would bring water tankers using his tractor to quench the thirst of cows and wild animals — a duty he considered both spiritual and moral. A few years ago, he married Nenu Kanwar, the daughter of Prabhu Singh Sewad from Kanodia Purahitan. Even after marriage, Shri Hari Singh's routine and behavior remained unchanged. His commitment to cow service, compassion for wildlife, and his role as an environmental protector (by planting and nurturing trees like Khejri, Ber, and Neem) only grew stronger.

He ran a small tea shop to support his family financially, and whenever he found time, he would often motivate the village youth, saying that protecting cows and wildlife is our duty. Shri Hari Singh had four children — two sons and two daughters.

On April 28, 2004, around 7 PM, just like any other day, Shri Hari Singh Rajpurohit left his home with his tractor to fetch a water tanker. While outside the village (in the Kankad area), he suddenly heard gunshots. Realizing that a poacher might be hunting wild animals, he followed the sound and found some armed men standing ready to hunt deer. These men were from a nearby area, and the main poacher was Oma Ram. Hari Singh recognized them and tried to stop the hunting. He said, “Do not kill these innocent creatures.” But the poachers ignored him and threatened, “Leave this place, or we will shoot you before we shoot the deer.”

Hari Singh, a man of extraordinary courage, did not back down. Instead, he challenged them and said:

“Yes, you may take my life.''
