We discussed item 27 in Islamic Manuscripts, Garrett Additional Box no. 20. This document of sale was written in 980 CE on behalf of the Coptic Christian Yuhānnis ibn Suqayna and his wife Maria, residents of the small town in the Fayyum called Buljusuq. They were buying a house from Maria’s father, Ibn al-Ḥillī. The document was registered by the notary Shuʿayb ibn Zakariyā and witnessed by several Muslims, including Muḥammad ibn Ḥisān ibn Dāwud who made a noticeable typo while writing his testimony.
