  • September 9[5] or June 17[6] – The Islamic prophet Muhammad, after being warned of a plot to assassinate him, secretly leaves his home in Mecca to make the Hijrah (emigrate) to Yathrib (later renamed by him Medina), along with his companion Abu Bakr. They take refuge in the Cave of Thawr south of Mecca for three days, departing on September 13 or June 21.
  • September 20[5] or June 28[6] – Muhammad does not enter Yathrib directly, but stops at its outlying environs of Quba. He establishes the Quba Mosque here, the first mosque of Islam. On July 2 (or September 24) he makes his first visit to Yathrib for Friday prayers.
  • October 4[5] or July 13 – After a fourteen days' stay in Quba, Muhammad finally moves from Quba to Yathrib, and is greeted cordially by its people. Here he drafts the Constitution of Medina, an agreement between the various Muslim, Jewish, Christian and pagan tribal communities in the city, forming the basis of a multi-religious Islamic state, and begins construction of the Al-Masjid an-Nabawi Mosque. Later during the caliphate of Umar in 638, the lunar year during which the emigration to Medina occurred (Friday 16 July 622 – 4 July 623) is designated "Year One" of the new Hijri era (Anno Hegirae – AH).
  • Xuanzang is fully ordained as a Buddhist monk at the age of 20.[7]

  • Summer – King Khosrau II plans an all-out effort against Constantinople. He returns to Anatolia with two armies of unknown size, presumably more than 50,000 men each. One of these (possibly commanded by Khosrau himself) is to contain Heraclius in Pontus; another under Shahin Vahmanzadegan is defeated by Theodore.

  • Spring – Byzantine–Sassanid War: Emperor Heraclius issues an ultimatum for peace to King Khosrow II, but he refuses his generous terms. The war-weary Persians revolt against Khosrow's regime at Ctesiphon, and install his son Kavadh II on the throne on February 25. He puts his father to death and begins negotiations with Heraclius. Kavadh is forced to return all the territories conquered during the war. The Persians must give up all of the trophies they have captured, including the relic of the True Cross. Evidently there is also a large financial indemnity. Having accepted a peace agreement on his own terms, Heraclius returns in triumph to Constantinople.[26]
  • Third Perso-Turkic War: The Western Göktürks, under their leader Tong Yabghu Qaghan, plunder Tbilisi (modern Georgia). The Persian defenders are executed or mutilated; Tong Yabghu appoints governors (tuduns) to manage various tribes under his overlordship.[27]
