"[2] Shaykh Nazim studied Classical Arabic and Islamic Jurisprudence (fiqh) in Istanbul, Turkey under Jamal al-Din al-Alsuni (d. 1955 CE/1375 AH) and received an ijaza (permission to teach) in these subjects from him.

He was initiated in Naqshbandi Sufism by Sulayman Arzarumi (d. 1948 CE/1368 AH), who eventually directed him to Damascus, Syria, to continue his studies with his destined sheikh.

The government had enacted laws forbidding the public performance of the Islamic call to prayer (adhan) in its traditional Arabic form.

The conflict was resolved with the coming to power of Adnan Menderes in Turkey, whose government chose a more tolerant approach to Islamic traditions.

[7] Notable students and followers of Al-Haqqani include John G. Bennett, the British author on spirituality,[8][9][10] and Rank Nazeer Ahmed, the Indian Muslim scholar and legislator.

[17] Shaykh Nazim can be seen addressing multitudes of Islamists in a conference of the Welfare Party whose audience includes the likes of Abdullah Gül, Recep Tayyip Erdoğan, and Necmettin Erbakan in Antwerp, Belgium in 1994.

[18] Nazim had been receiving medical care since April 17, 2014, when he was rushed from his home in Lefke to the Near East University Hospital in North Nicosia, Northern Cyprus, after suffering from respiratory problems.
