He was born in Kayseri and died in Darende. He taught at the Ulu Camii (The Great Mosque) where he was installed by Sultan Bayezid I after it was completed. Somuncu Baba's students included Molla Fenari and Hacı Bayram-ı Veli.
Somuncu Baba is one of the virtuous men who came to Anadolu for spiritual conquest, he was also a descendant of Islamic prophet Muhammad After receiving an education in cities which are the center of knowledge like Şam, Tabriz, Erdebil, he settled in Bursa for his guidance and duty. He taught at the Bursa Grand Mosque where he was installed by Sultan Bayezid I after it was completed. For hiding his sipiritual side, he baked bread and sold them so he was known as Somuncu Baba. He became known after he had translated the sura of Al-Fatiha, in seven different ways during the opening of Bursa Grand Mosque, in Bursa. He avoided becoming famous so he left Bursa and moved Aksaray. He left his son Yusuf Hakiki Baba in Aksaray and he went to Mecca with his son Halil Taybi when they got back to Anadolu they settled in Darende and he died here in 1412. His tomb is still in Darende.
