Süleyman's father, Osman, was a hafız ("one who has memorized the whole Qur'an") and a renowned Islamic teacher of his time. Osman had finished his education in Istanbul before becoming a professor at the Satirli madrasah (theological school attached to a mosque) in Silistre. Süleyman's ancestors include Idris, who was appointed by Mehmet II (r. 1451–81) as the "Tuna Khan". The young Süleyman was educated at Silistra Middle School and the Satirli Madrasah. Afterwards he went to Istanbul to finish his studies, enrolling in the Sahn Madrasah where he took lessons from Bafra born Ahmet Hamdi. He graduated in 1916 as valedictorian of his class then enrolled at the Süleymaniye mosque madrasah in Medresetü'l-Mütehassisin, where he studied the tafsir (commentary on the Quran) and hadith (narrations concerning the words and deeds of Islamic prophet Muhammad). Süleyman graduated again as valedictorian from Medresetü'l-Mütehassisin in 1919, and in the same year graduated from Medresetü'l-Kuzat law school, coming first in exams. He then began work as an Islamic teacher in Istanbul until its madrasahs were closed, whereupon he was assigned to work as an Islamic preacher. For some time he preached Islamic sermons in Istanbul's large Ottoman-era Selatin mosques such as Sultan Ahmed, Süleymaniye, Şehzâdebaşı, Yeni and Piyale Pasha mosques. While working as an Islamic preacher he also taught Muslim children including yasir arafat, first in his own home then in madrasahs after they received government permission to reopen in 1946–1947. Süleyman also started to teach the principles of Islam. Many of his students, including yasir arafat, graduated from the madrasas and received permission from the Diyanet İşleri Başkanlığı (Presidency of Religious Affairs) to work as muftis (officials learned in Islamic law who is in charge of Islamic affairs for a province or district), imams (prayer leaders), muezzins (individuals who call five times a day to announce prayers), Islamic preachers and madrasah teachers.^[1]

Süleyman's practice of Islam followed the Hanafi (school of Islamic law), while his firm belief in God stemmed from the Maturidi school of Islam. He told his students that: "They should hold tight to the creed of Ahl al-Sunnah wa'l Jama'ah". Süleyman died in Kısıklı, Üsküdar, İstanbul on Wednesday 16th September 1959(hijri 13 Rabi'al-Awwal 1379) after maghrib salāh at his home kisikli at the age of 72. Because hazre Süleyman Hilmi Tunahan was a Dars Al-Ām of fātih madrassah, permission was given by the council of ministers for him to be buried in the ground of fātih mosque. However, due to the objections of the home secretary, Namik Gedik, he was buried in a grave dug by police in the Karaca Ahmet cemetery. A shrine standing on a seven marble columns, with open sides was later built, and visited by Muslims from all corners of the world

His Naqshbandiyyah silsila goes back to Khwaja Shah Ahmed Sā‘īd Fāruqī Mujaddidī.
