Dr. Israr Ahmad was born on April 26, 1932 in Hisar (a district of East Punjab, now a part of Haryana) in India, the second son of a government servant. He graduated from King Edward Medical College (Lahore) in 1954 and later received his Master's degree in Islamic Studies from the University of Karachi in 1965. He came under the influence of Abul Ala Maududi as a young student, worked briefly for Muslim Student's Federation in the Independence Movement and, following the creation of Pakistan in 1947, for the Islami Jamiyat-e-Talaba and then for the Jamaat-e-Islami. Dr. Israr Ahmad resigned from the Jama`at in April 1957 because of its involvement in the electoral politics, which he believed was irreconcilable with the revolutionary methodology adopted by the Jama'at in the pre-1947 period.
In 1971 Ahmad gave up his medical practice to devote himself full time to the Islamic revival. In 1972 he established or helped establish the Markazi Anjuman Khuddam-ul-Qur'an Lahore, Tanzeem-e-Islami was founded in 1975, and Tahreek-e-Khilafat Pakistan was launched in 1991.
While still a student and an activist of the Islami Jami`yat-e-Talaba, Dr. Israr Ahmad gained considerable fame and eminence as a Mudarris (or teacher) of the Holy Qur'an. Even after resigning from the Jama`at, he continued to give Qur'anic lectures in different cities of Pakistan, and especially after 1965 he has, according to his own disclosure, invested the better part of his physical and intellectual abilities in the learning and teaching of the Qur'anic wisdom.
