He is also the son of Sultan Haski Mosque, the muezzin Ali Effendi AH. 1052 / m. He was born in Istanbul in 1642. As a child, he received an excellent education under the patronage of Koprolozad Fazil Mustafa Pasha. On the other hand, he was taking speech lessons from the great dervish. Later, on the advice of his tutor, he continued his conversation with one of his pupils, Suyolcuzade Mustafa Eyyubi Efendi, at H. 1070/M. in 1659. Though he was only eighteen years old, he was given the leave.
Hafiz Osman, who devoted his entire next life to writing, gained strength in writing in a short time and began practicing the style of Sheikh aklam-ı sitte of Nefeszade Seyyyid İsmail Efendi anew. In the meantime, he was studying the works of Sheikh Hamdallah and trying to understand the intricacies of his style. Finally, by proving his maturity with the Qur'an which he wrote in imitation of Sheikh Hamdallah, he reached the rank of Sheikh art.
Meanwhile, Hafiz Othman, who had joined and mastered Seyed Alaeddin Effendi, a sheikh of the Sanboli community, began to invent his own dialect during his 1672 trip to Cairo to visit the Khanka of Wissam Shanboli. His trip to the Hejaz in 1676 to perform the Hajj was a turning point in his art.
Hafiz Othman, who revealed a new way of mindfulness with his impressions here, waited until the death of his master, Navishda Seyyed Ismail Effendi, in 1679. However, after that, he began to write in a new style that relatively eliminated the influence of rubies in Sheikh Hamdullah's writings, and made the form of The letters and their position very simple.
Hafeez Osman, who was famous for his new style which was adopted in a short time and still followed in calligraphy despite his criticism at the beginning, was appointed as a calligraphy teacher to Sultan Mustafa II at the end of 1694. Sultan Mustafa, who shows respect for his teacher and participates in their conversation in the Ihram dress, is enough to carry an inkwell while writing, the district of Plovdiv - Diyarbakir - according to a rumor - gives a reward for this duty.
Hafiz Othman, who lived all his life as a simple dervish and shunned adornment and ostentation, turned away from his beloved art because he was paralyzed in his last days, and finally died on December 3, 1698. After a funeral prayer held at the Sünbül Efendi Lodge, where he continued all his life, he was buried in a hut of Dervishes, and the inscription made by Ağakapılı İsmail Efendi on his tombstone.
