Early Quranic manuscripts
The Topkapi manuscript is an early manuscript of the Quran dated to the early 8th century. This manuscript is kept in the Topkapi Palace Museum, Istanbul, Turkey. It was wrongly attributed to Uthman Ibn Affan (d. 656), but judging from its illumination, the Topkapi manuscript does not date from the period (mid 7th century) when the copies of the Caliph Uthman were written.
