Muhammad Din Tahir (1942–2008) known as M.D. Tahir was born in 1942 in a gujjar family in the small village Takoli, in the district of Ambala. His mother died a few months after his family's migration to Sargodha in Pakistan in 1947. His father also died when he was only 7-years-old, leaving Tahir and his sister Hashmat as orphans. After the death of their parents, neither orphans had any means of earning money. He started studying under the street lights and sold milk and ice which was useful to earn a little money. Under these circumstances, Tahir continued his study and graduated from Zamindara College in Gujrat, Punjab, and thereafter attempted for LLB, the law degree in which he succeeded and became a lawyer after passing the LLB exams from Punjab University. He started his practice as a lawyer in 1972 and soon became a prominent lawyer in Pakistan. He was appointed special commissioner to record the statement of the Chief Martial Law Administrator of Pakistan, Yahya Khan, after the end of his regime.

Mr. Tahir was the first Pakistani lawyer who moved countless writ petitions in the Lahore High Court Lahore as well as in the Supreme Court of Pakistan for sake of poor people rights. He also moved submissions to the International Court of Justice against cruelties of the war in Iraq, Palestine, Kashmir, and around the world. He died on 20 April 2008 of cardiac arrest on Sunday night at the age of 65 in Lahore and buried in the side area of a mosque for which he trusted his land and funded that mosque to be built
