Ömer Nasuhi Bilmen (1883–1971) was a Muslim scholar of fiqh and tafsir, and the fifth president of the Directorate of Religious Affairs of the Republic of Turkey. He is known for his expansive work on a concise manual on Islamic faith, worship and ethics called The Big Book of Islamic Catechism (Büyük İslâm İlmihali).[1] [2]

Upon his father's death when he was a child, he was raised under the patronage of his uncle Abdürrezzak İlmî Efendi at the Erzurum Ahmediyye Madrasa. He studied under his uncle and the mufti of Erzurum, Narmanlı Hüseyin Efendi. When his two teachers died at close intervals, he moved to Istanbul in 1908 and in 1909 started attending the classes of Tokatlı Şâkir Efendi, one of the Fatih Mosque lecturers. In addition, he passed the exam of Attorney General in 1912 and graduated from the School of Judges (Medreset ul-Kudât) he was attending in 1913.[3]
