Fatwas Ahmadis Mirza Ghulam Ahmad of Qadian claimed to be the Messiah, Prophet, and Mahdi awaited by some Muslims as well as a Ummati Nabi, a subordinate prophet to Muhammad who came to restore Islam to the pristine form as practiced by Muhammad and early Sahaba. Khan declared Mirza Ghulam Ahmad a heretic and apostate and called him and his followers disbelievers (kuffar). Deobandis The theological difference with the Deobandi school began when Maulana Ahmed Raza Khan Qadri objected in writing to some of the following beliefs of Deobandi scholars. A founder of the Deobandi movement, Rashid Ahmad Gangohi stated that God has the ability to lie. This doctrine is called Imkan-i Kizb. According to this doctrine, because God is omnipotent, God is capable of lying. Gangohi supported the doctrine that God has the ability to make additional prophets after Muhammad (Imkan-i Nazir) and other prophets equal to Muhammad. He opposed the doctrine that Muhammad has knowledge of the unseen (Ilm e Ghaib).

Khan collected scholarly opinions in the Hejaz and compiled them in an Arabic language compendium with the title, Hussam al Harmain ("The Sword of Two Sanctuaries"), a work containing 34 verdicts from 33 ulama (20 Meccan and 13 Medinese). This work initiated a reciprocal series of fatwas between Ahle Sunnat (Barelvis) and Deobandis lasting to the present.

He considered most Shiites of his day apostates because, he believed, they repudiated necessities of religion. Wahabi Movement Ahmed Raza Khan declared Wahabis as disbelievers (kuffar) and collected many fatwas of various scholars against the Wahhabi movement founded by Muhammad ibn Abd al-Wahhab, who was predominant in the Arabian peninsula, just as he had done with the Ahmadis and Deobandis. Until this day, Khan's followers remain opposed to the Wahhabi and their beliefs. Permissibility of currency notes In 1905, Khan, on the request of
