Is Jerusalem mentioned in the Koran?

Answer 1

No,

Jerusalem is not mentioned in the Qur'an

Nor is it mentioned by its Arabic translation, "Al Quds".

Some Scholars believe the Qur'an verse 17:1 is interpreted by Islamic tarsiers as referring to the "The farthest place" (al-aqsa) which is identified in Islamic tradition with Jerusalem, but there is still no mention of Jerusalem in that verse or in any other Qur'anic verse.

But then again, Muhammad is mentioned in the Koran only one time by name, only once, and yet there are many references to Muhammad in the Koran without mentioning his name. Solomon in the Koran (Solomon is mentioned in the Koran over 20 times) mention the building of the Jewish temple; the stories of Moses and the Exodus (Moses is mentioned over 160 times) refer to finding the holy land and the promise land for the Hebrews; the Kingdom of David (King David is mentioned 17 times); the mount of olives is sworn by in the quran; Also the farthest house of worship (the holiest Jewish temple in Jerusalem) is mentioned several times, in one instance to explain why Muslims should no longer face towards Jerusalem in Prayer.

so many events that The Bible describes taking place in Jerusalem while mentioning it's name explicitly (including Christ's Passion) are also described in the Koran though the place name is not mentioned. This does not belittle Jerusalem's place in Islam, just as the once only mention of Muhammad's name explicitly in the Koran does not diminish his place in Islam. Furthermore, The most mentioned (explicitly) place name in the Koran is "Egypt" but this does not mean Egypt is holy in Islam or diminishes Mecca as place in Islam one iota.
