I made a video last year on this topic, that summarizes a number of previous Al Quds posts I've written.
Here is a roundup of posts I've made to celebrate Qods Day over the years:
Introduction - An overview of how Muslims have ignored Jerusalem when they had control over the city.
The originator of Qods Day: A brief snippet of another, rather disgusting, legal ruling by the late Ayatollah.
A 1910 article showing the tremendous growth of Jerusalem in the few decades since mass Jewish return to the city, including how much land values increased and how much money Arabs were getting for selling land to Jews.
Jerusalem in Islamic art: A survey of the (non)-existence of Jerusalem in any Islamic art that pre-dates Zionism, compared to some ancient Jewish pictures of Jerusalem.
Jerusalem in Islamic poetry: A very similar posting showing every ancient Islamic poem I could find that mentions Islam's "third holiest city," plus a 12th century Jewish poem about the city.
Jerusalem in Islamic coins: Another post comparing the number of times Jerusalem was depicted in historic Islamic coins compared to ancient Jewish currency.
Jerusalem in Islamic prayer: Jerusalem, for some strange reason, is not mentioned once in Islamic prayer, but it is a central motif of Jewish prayer.
