Mushtaq Qadri was born on 18th of the month of Ramadan, 1386 A.H. (approximately 1 January 1967), in Banoon Khyber Pakhtunkhwah, Pakistan. His father's name was Akhlaq Ahmad. Before permanently moving to Karachi, he lived in Faisalabad.
In 1991 Mushtaq Qadri got married. His nikah (matrimonal ceremony) was conducted by his mentor Muhammad Ilyas Qadri. He has four children: Obaid Raza Attari; Abdul Mustafa Attari; Faizan Attari; and Ashfaq Attari.
Mushtaq Qadri Attari was an associate of the spiritual guide and leader Maulana Muhammad Ilyas Qadri, the head of the world's largest "Non-Political "Islamic movement Dawat-e-Islami.
In 1986 Mushtaq Qadri gave his spiritual allegiance (bay'ah) to Silsila (Link)Qadriya. He is considered as a mentor of Owais Qadri.
Mushtaq Attari had never accepted payment for reciting na'at poems. Recording companies had offered him handsome amounts for releasing his albums, but he had refused. He would never ask for a ride to take him to programs where he was invited for reciting, nor would he accept money for taxi fare. He never accepted any money made from his recordings, and any proceeds would be forwarded toward funding Dawat-e-Islami righteous projects.
Towards the end of life, Mushtaq Qadri was suffering from throat and chest cancer, and could no longer speak. His spiritual guide, Ilyas Attar Qadri, who was in the United Arab Emirates at that time, phoned him and told him to recite the kalima (declaration of faith) and Mushtaq Qadri found himself, surprisingly, able to do so. Mushtaq Qadri died on 29th Sha'aban 1423 A.H. (5 November 2002) in Karachi.
Upon hearing about his death, Muhammad Ilyas Attar Qadri immediately returned to Karachi from the Emirates. The funeral prayer of Mushtaq Attari was offered in Nishtar Park, Karachi, led by Qadri, the founder of Dawat-e-Islami. Mushtaq Attari was buried in Sahrā-e-Madinah (near Toll Plaza, Karachi).
