Husamul Haramain (Ḥusām al-Haramayn) or Husam al Harmain (The Sword of the Two Holy Mosques) 1906, is a treatise written by Ahmad Raza Khan (1856- 1921) which declared the founders of Deobandi, Ahle Hadith and Ahmadiyya movement as heretics.
In 1905, Khan performed pilgrimage to holy sites in the Hijaz. During this period, he prepared a draft document entitled "Al Motamad Al Mustanad" (The Reliable Proofs) in which he argued against opinions of founders of Deobandi, Ahle Hadith and Ahmadiyya movement for presentation to his contemporaries in Mecca and Medina. Khan collected scholarly opinions of thirty-three fellow scholars' verdicts. All of them concurred with his assertion that the founders of Deobandi, Qadiyani and Ahle Hadith movements were apostate and blasphemers. They also exhorted the government of British India to execute the founders of those movements for heresy.
The fatwa deals separately regarding each of the following:
Ashraf Ali Thanvi, Rasheed Gangohi and Qasim Nanotvi were the main figures stated as infidels as a part of Deobandi movement due to showing blasphemy against the Allah, Prophet Muhammad and the Awliya.
Mirza Ghulam Qadiyani, the founder of Ahmedi movement declared as infidel due to violation of the belief regarding the finality of Prophethood at Muhammad.
