Hizbul Ahrar was formed in Nangarhar province of Afghanistan on 12th November 2017 when disgruntled members of Jamaat-ul-Ahrar under the command of Mukarram Mohmand, also known as Mukarram Khan and Omar Khurasani, announced the formation of a new group. The announcement was made through a video statement. Mukarram had earlier served as an important commander and spokesman for the Jamaat-ul-Ahrar group. The video statement also said that Mukarram Mohmand left Jamaat-ul-Ahrar over differences with its chief Umar Khalid Khurasani over attacks against innocent minority Christians, killing civilians, extortion, kidnapping for ransom and other acts he deemed un-Islamic. In this respect, he particularly mentioned terrorist attacks against National Database and Registration Authority (NADRA) office in Mardan, attack on security forces at Wahga border, attacks in Gulshan-e-Iqbal Park Lahore, which claimed the lives of many Christians, and other such attacks carried out around the country. He said that these terrorist attacks had cost the lives of innocent people, including women and children. In the video Khurasani recalled that Jamat-ul-Ahrar had claimed responsibility for all these deadly attacks. Mukarram claimed that he had made attempts to bring reforms in the militant group, but failed to achieve any success. He said that it led him take part ways with the JA and create his own group. He accused Khalid Khurasani of attacking him one week back, in which he was also injured.
In the same video statement, he claimed that a number of leading commanders have also announced disassociation from Jamaat-ul-Ahrar, and now they were a part of Hizbul Ahrar. Some important names in the newly created group included: Hizbul Ahrar Military Wing chief Jihadyar Mehsud, Financial Commission head Commander Muslimyar, Political Commission chief Haji Rashid, Mohmand Agency Commander Imran Aurakzai, and Qari Ismael Afridi of Khyber Agency. Mukarram Mohmand named Dr Aziz Yousafzai as the spokesman for his new group.
On 24th April 2018, Hizbul Ahrar announced the launch of its Operation Ibne Qasim against Pakistani security forces with a major suicide attack in Quetta involving three suicide bombers. The accompanying claim for the attack included the announcement of the launch of Op Ibne Qasim. According to the statement by Hizbul Ahrar spokesman, the group’s target in this operation would be Pakistani security forces while it promised not to harm civilians. Since then, Hizbul Ahrar has released a video and multiple infographics on its Operation Ibne Qasim. Hizbul Ahrar has also released an album of Jihadi anthems glorifying its Operation Ibne Qasim.
