The earliest mosque erected was that at Mecca, which consisted of a great court, in the centre of which was the Ka`ba or Holy Stone.
After the burning of the Ka`ba during the siege of Mecca by Hosain b.
The siege was raised in the third month on the news of the death of Yazid, but not before the Ka`ba had been destroyed.
In the centre of the town stands Meshed (strictly Meshhed) `Ali, the shrine of `Ali, containing the reputed tomb of that caliph, which is regarded by the Shi`ite Moslems as being no less holy than the Ka`ba itself, although it should be said that it is at least very doubtful whether `Ali was actually buried there.
He was originally called Abd-el-Ka`ba ("servant of the temple"), and received the name by which he is known historically in consequence of the marriage of his virgin daughter Ayesha to Mahomet.
