what year is considered the beginning of islam
Islamic calendar The Islamic calendar employs the Hijri era whose epoch was retrospectively established as the Islamic New Year of AD 622. During that year, Muhammad and his followers migrated from Mecca to Yathrib (now Medina) and established the first Muslim community (ummah), an event commemorated as the Hijra. In the West, dates in this era are usually denoted AH (Latin: Anno Hegirae, "in the year of the Hijra") in parallel with the Christian (AD) and Jewish eras (AM). In Muslim countries, it is also sometimes denoted as H[1] from its Arabic form ( سَنة هِجْريّة, abbreviated هـ). In English, years prior to the Hijra are reckoned as BH ("Before the Hijra").[2]
Baghdad Located along the Tigris River, the city was founded in the 8th century and became the capital of the Abbasid Caliphate. Within a short time of its inception, Baghdad evolved into a significant cultural, commercial, and intellectual center for the Islamic world. This, in addition to housing several key academic institutions (e.g., House of Wisdom), garnered the city a worldwide reputation as the "Centre of Learning".
Kaaba The Quran contains several verses regarding the origin of the Kaaba, it states that the Kaaba was the first House of Worship, and that it was built by Ibrahim and Ishmael on God's[citation needed] instructions.
Timbuktu Timbuktu was a world centre of Islamic learning from the 13th to the 17th century, especially under the Mali Empire and Askia Mohammad I's rule. The Malian government and NGOs have been working to catalog and restore the remnants of this scholarly legacy: Timbuktu's manuscripts.[70]
