But now it is common to refer to a specific structure with the silver dome occupying the southern edge of the Temple Mount as the Masjid al-Aqsa, but that structure did not exist when the Quran was revealed. The specific structure which is now commonly called Masjid al-Aqsa (with the silver dome) was built by an Omayyad ruler. And the Temple Mount in its entirety is now commonly referred to as simply al-Haram al-Sharif (The Noble Sanctuary).
But as I said, what the Quraan refers to as Masjid al-Aqsa is not any particular structure but the entire Temple Mount and vicinity that was the place of worship built by King Solomon.
