Mecca is the "capital" of Islam. Jerusalem has no place in it whatsoever. Not mentioned a single time in the Quran. Only centuries later, for political reasons, was the "Noble Sanctuary" nonsense added.
“Politically, Jerusalem is our capital; in our religion, it is our capital; geographically, it is our capital.”
Religiously - the very name/word “Jerusalem” is NEVER MENTIONED IN THE KORAN. From this perspective, Jerusalem is a non-entity in the Moslem religion. Moslem religious claims to the Temple Mount in Jerusalem are of very recent (i.e. political in nature) origin, being non-existent prior to the 1930s: http://www.eretzyisroel.org/~jkatz/templemount.html
Geographically - what a joke! When Jordan had unfettered control over East Jerusalem, it didn’t make its own capitol there, nor did it grant the so-called “Palestinians” (Fakestinians is a more accurate description, followed closely by Shitholeistinians) any kind of autonomy with East Jerusalem as its capitol. Again, no Arab or Moslem nation EVER had Jerusalem as its capitol, so this argument is a (not so good) canard.
