Abdul Sattar Haq Nisar is a cleric and the Head and a teacher at Madrassa Tanweer-ul-Afkar in Aibak, Samangan Province. He is a staunch follower of the fundamentalist Hanafi-Deobandi School of thinking. He was arrested by NDS 20110309 for unknown reasons and brought to Kabul for questioning. Students and religious scholars staged a demonstration on 20110313 for the release of the cleric. The students asked the shop keepers to close their shops or they would be ransacked. So the whole Bazar in Aibak City is closed.
In 2010, two teachers and four students of Tanweer-ul-Afkar madrassa disarmed a police checkpoint and joined militants in Zhwandun Valley. A resident, who did not want to be named, said, the two teachers who joined the Taliban were Nisar's relatives.
