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.
Relic
While various relics are preserved by different Muslim communities, the most important are those known as The Sacred Trusts, more than 600 pieces treasured in the Privy Chamber of the Topkapı Palace Museum in Istanbul.
