"The best tribute to her is to continue her fight for human rights and democracy", tweeted Pakistani Nobel Peace Prize laureate Malala Yousafzai, adding she had met Jahangir just last week in Oxford.
She was not only a symbol of bravery and strength for the people of Pakistan but also an inspiration for women across the globe. She was appointed UN Special Rapporteur on Extrajudicial, Arbitrary or Summary Executions and later as the UN Rapporteur of Freedom of Religion or Belief. Her daughter Muneezay Jehangir is a TV anchor.
Punjab Chief Minister Shahbaz Sharif tweeted: "Pakistan has lost a passionate champion of human rights and a staunch supporter of democracy..."
She also pressed for legal reforms to protect the rights of bonded laborers, who often spend years trapped by debt to owners of brick quarries, textile looms or wheat fields, and she lobbied for the enforcement of widely ignored laws against child labor. Her sister Hina Jilani has rightly said it is a loss for everyone as she took up cases of the voiceless.
She often had a tempestuous relation with the Pakistani state.
President Mamnoon Hussain, Chief Justice of Pakistan Saqib Nisar along with other politicians, lawyers and journalists have expressed grief over Jahangir's death. She remained house arrest in 2007 for nine days.
Akhtar called Asma "undoubtedly the bravest and the most resilient fighter for human rights".
Asma was arrested in 2007 by the government of the then military dictator Pervez Musharraf, and in 2012 claimed her life was in danger from the country's top spy agency Inter Services Intelligence (ISI).
The people of South Asia, as well as followers of her work world-over, are mourning the sudden death of Jahangir who was recognised for her activism, particularly surrounding human rights, women's rights, and minorities rights in Pakistan.
She has received several awards, including a Hilal-i-Imtiaz and a Sitara-i-Imtiaz in 2010.
Internationally, she was awarded the UNESCO/Bilbao Prize for the Promotion of a Culture of Human Rights, an Officier de la Légion d'honneur by France, the 2010, Martin Ennals Award for Human Rights Defenders, and the Ramon Magsaysay Award. She was courageous, fearless, invincible.
