Mamman Khan was born to Mohammed Hanif on April 4, 1967 in the village of Bhadas, Ferozepur Jhirka. He completed high school at a small school in his hometown before enrolling in Civil Engineering at Bengaluru University, Karnataka in 1994. Mamman Khan also worked for DLF, a commercial real estate development company, for a while before launching a hugely successful construction supply firm.[citation needed]
When speaking in the Haryana Legislative Assembly in February 2023, Mamman Khan displayed photographs depicting acts of violence allegedly by the cow vigilante, Monu Manesar. Mamman Khan raised concerns on Nasir and Junaid's incident, who were killed on the suspicion of cattle smuggling, were burnt by "influential” cow vigilantes and later they brutally thrashed them and handed them over to Ferozepur Jhirka police in Haryana, which is also Mamman Khan's constituency.[7] This speech was not considered of any major significance until the 2023 Haryana Riots which took place in the Nuh district of Haryana, on 31 July 2023. During the riots, Mamman Khan was accused for instigating violence in the Nuh by the Home Minister of Haryana. Manohar Lal Khattar, also indirectly mentioned Mamman Khan when he said that “fingers are being pointed at some other Congress MLAs” in connection with the Nuh violence and added that absence of a response from the opposition party certainly proves that “something is suspicious"
Mamman Khan was called in front of the Special Investigation Team for an investigation into his involvement in the 2023 Haryana Riots to the Nagina village police station in Nuh. Six months proceeding the Nuh violence, Mamman Khan was later charged under the Unlawful Activities (Prevention) Act. Police had earlier accused Khan of inciting violence and being in touch with those involved in sharing provocative posts on social media platforms. Besides, he also faces some other charges in the FIR. This decision was heavily opposed by Bhupinder Singh Hooda and other members of the Indian National Congress. [8][9][10]
