When did Islam start

 

When did Islam start, and how long was the period between
Jesus
(upon whom be peace) and Muhammad
(peace
and blessings of Allaah be upon him)?

Praise be to Allaah.

Islam began with the beginning of the
Prophet's mission, when Jibraa'eel (the Archangel Gabriel) brought down the
Revelation from Allaah in Makkah (Mecca) in the Arabian Peninsula. This occurred
on a Monday in the month of Ramadaan, in the fortieth year of the Prophet
Muhammad's (peace and blessings of Allaah be upon him) life, thirteen years
before his Hijrah (migration) to Madeenah (which marks the beginning of the
Islamic or Hijri calendar). According to the Gregorian calendar, the beginning
of the Prophetic mission happened around 608 or 609 CE. Salmaan al-Farsi, may
Allaah be pleased with him, one of the Companions of the Prophet (peace and
blessings of Allaah be upon him) reported that between Muhammad (peace and
blessings of Allaah be upon him) and Jesus (peace and blessings of Allaah be
upon him), there were six hundred years.

And Allaah knows best.
