He was one of the rich people in Barla when the Master was exiled to Barla. He was a merchant, hafiz and Muslim preacher-scholar clergyman at the same time.   He was from “evlad-ı fatihan” (the Balkan Turks) of Hungary and known as “Hafiz Ahmet, the Immigrant” because he immigrated to the Anatolia.  He hosted the Master for almost one week when he first came to Barla. He repeatedly told his wife: “This is a godsend. We must satisfy Bediüzzaman no matter what. He should be pleased as he leaves Barla.”  He tried to properly host the Master.  And Bediüzzaman said the following to indicate to his sincere services: “… served me for eight years with devotion and worked for the Epistles of Light together with his family, grandchildren and spouse and sons-in-law…”  He passed away in 1948. He was buried in the graveyard in Barla.

He was ‘the first student of the Epistles of Light’ as described by the Master who said “Hulusi is always the first”, “The first addressee is Hulusi”. He was born in Harput, Elazığ in 1896. He started to study at Rüştiye Askeriye (military school) in Elaziz and then went to Kuleli Military High School. As he started studying at the Military College the World War I began and he joined the forces in Caucasian frontline in Çanakkale.  He was injured on the face, chest and left arm during Çanakkale War. He took part in the Turkish War of Independence. He retired in 1950 when he was a colonel. Mr. Hulusi met the Master in 1929 for the first time.  Then he became the Master’s the most eager student in saff-ı evvel, and a beloved, loyal, hard-working, serious, genuine afterlife companion and a patient friend of the Master who was benevolent in the faith service.   ‘Brother Hacı Hulusi’, who paved the way for the emerge of the Letters with the questions he asked, continued serving the faith and Koran cause uninterruptedly without slowing down throughout his blessed lifetime which was almost a century long. He was buried in the family graveyard in Harput, Elazığ.

He was one of the first clerks and students of Bediüzzaman. He was born in İskodra, Albania in 1906. He retired as a captain. He was held in the prison together with Bediüzzaman in Eskisehir and Afyon respectively in 1935 and 1943. Refet Barutçu contributed to the writing of some important epistles with the questions he asked to the Master who called him “my beloved, honest, serious, sincere afterlife companion who works in Hizmet-i Kuraniye (all the efforts of protecting the greater cause of the God).”   Refet Barutçu, who wrote hundreds of the Epistles of Light books and taught Koran to thousands of people, served the faith and Koran cause to the last day of his life.  He died in 1975, Ankara.
