# Muhammad leaves Mecca for Yathrib in the Hijra that later calendars take as year one

Date: 622

## The fact

In 622 CE Muhammad left Mecca for Yathrib in the Hijra that later Islamic calendars take as year one. The move is a received forced emigration, not a tourist itinerary. Muhammad's documented role is: He left Mecca under threat and entered Yathrib. Companions emigrated; Quraysh pressure is the received cause.

## Context

Abu Bakr is the companion of the road in the standard telling. The town later called Medina received him. Sharing the emigration with those who left is required. A mosque door photograph is still not his face. The setting of Muhammad leaves Mecca for Yathrib in the Hijra that later calendars take as year one is the public file around 0622-07-16. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Driver [forced-displacement-scale](/drivers/forced-displacement-scale) is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
