Mecca
The holy book of islam is "Quran" . Makkah (mecca) is the holy city for beleivers of Islam (muslims)
The city of Mecca and the city of Madina are both holy cities of Islam.
There is no 'Muslim capital' because Muslims live in different countries with their differing capitals all around the world. However, the 'point of adoration', the Qibla is Mecca where the Kaaba is.
Mecca is the most holy site of Islam.
The motto of Mecca is 'Holiest city in Islam'.

mecca is the place Islam emerged and started and was the city of prophet Muhammad (PBUH)
Mecca (Makka), the holiest city in Islam is located in the Kingdom of Saudi Arabia.
Mecca is important in Islam, it has no signifiance in Buddhism
I believe Islam started in mecca but the Muslims were pushed out to Medina where it started to gain support, then they returned to mecca and eventually took control.
Islam is not a place, it is a religion.
