[3] Abdul Haq was born in the city of Akora Khattak, Peshawar District, North-West Frontier Province (NWFP), British India, the son of Haji Maruf Gul, a local landlord, businessman, and religious scholar.

[2] Muhammad Akbar Shah Bukhari, however, writes in Akabir Ulama-i Deoband that he was born on "7 Muharram al-Haram 1327 AH, Sunday, corresponding to January 1910".

"[6] He completed daurah of hadith, the final stage of the Dars-i Nizami curriculum, under the supervision of Sayyid Husain Ahmad Madani, receiving his sanad-i faraghat (graduate degree) in 1352 AH (1933/1934).

[4] Abdul Haq returned to Akora Khattak and, on the instruction of his father, opened a small madrasah in a mosque adjacent to his house in order to provide a basic and religious education to the children in the area.

[6] In the first year, many madrasah students who were unable to return to India came to Darul Uloom Haqqania to complete daurah of hadith with Abdul Haq.

In his lectures, he stressed the importance of the concept of finality of prophethood and argued against the interpretations of Quranic verses and hadiths used by Ahmadis to support their beliefs.

He was one of the signatories of the resolution moved on 30 June 1974 in the National Assembly in support of declaring Ahmadis as non-Muslims in Pakistan.

[2][11][12] When the Soviets invaded Afghanistan in 1979, Abdul Haq declared the Afghan resistance to be a jihad and an ideological struggle between Islam and communism.

He gave bay'ah at the hands of other Sufis including Husain Ahmad Madani, Khawaja Abdul Malik Siddiqi, and the Faqir of Ipi.

[2] Abdul Haq died on 7 September 1988, at the age of 74 or 76, at Khyber Teaching Hospital in Peshawar, NWFP, Pakistan.
