Jahangir was born in Lahore in January 1952. She was also the first female president of Pakistan's Supreme Court Bar Association and had won several awards including the Unesco/Bilbao prize for the promotion of a culture of human rights and the French Legion of Honour.
More recently she spoke out against BBC Persian journalists being put on trial in Iran, as part of her role as United Nations special rapporteur on human rights in Iran.
After her graduation from the prestigious Kinnaird College and LLB from the Punjab University in 1978, she hit the headlines when she enthusiastically jumped into the Movement for Restoration of Democracy (MRD) against the Zia ul-Haq dictatorship and was jailed.
As the news of her death broke, condolences started pouring in from lawyers, rights activists and politicians. As a daughter, mother and legal expert, she had left irremovable imprints on the judicial and political history of Pakistan, he remarked.
In a statement on Sunday, PM Abbasi lauded Asma's contributions towards upholding rule of law, democracy and safeguarding human rights.
"The generals and judges will be happy to see that now there is no one who can fight like Asma Jahangir", Naveed said.

"It is a tribute to a large number of Pakistanis who have worked relentlessly for better human rights in the country", she said.
Chief Justice of Pakistan (CJP) Mian Saqib Nisar, former premier Nawaz Sharif, Punjab Chief Minister (CM) Shehbaz Sharif, Senator Aitzaz Ahsan, Chief Election Commissioner Sardar Muhammad Raza Khan and others expressed condolences over Asma Jahangir's demise.
Ousted prime minister Nawaz Sharif spoke about Asma's work for women and stance against dictators, saying it would be hard to fill the void left by her death.
Nobel prize victor Malala Yousafzai remarked: "Heartbroken that we lost Asma Jahangir - a saviour of democracy and human rights".
Daily Times Editor Raza Ahmad Rumi called her a "hero".
Few Pakistani rights activists have achieved the credibility of Jahangir.
A fierce defender of democracy, she often criticized Pakistan's military and intelligence.
Jahangir is also a recipient of the 2010 Freedom Award and 2014 Right Livelihood Award.
"She was courageous and dedicated rights and social activist and above all the voice of the voiceless", said he.
