Uthman ibn Affan

The standardization of the Quran under Caliph Uthman (644–656 CE) was a defining act of early Islam. Undertaken around 650 CE to address regional differences in recitation, it produced the Uthmanic codex that became the basis for all later manuscripts used by Muslims worldwide.

The Treaty of Hudaybiyyah (628 CE / 6 AH) was a ten-year truce between the Muslims of Medina and the Quraysh of Mecca. Though its terms seemed to favor the Quraysh and many companions opposed it, within two years it fueled the community's rapid growth and the near-bloodless entry into Mecca.
