The Al-Aqsa Masjid which is the third most important place in the world for Muslims, is different from the Dome of the Rock, which also has religious significance for Muslims, and is called the Masjid Qubbat As-Sakhrah, but it is not Al-Aqsa Masjid.
These are two completely separate structures. And this is a common mistake amongst Muslims. Since they are located in the same complex, people assume that the Dome of the Rock is Al-Aqsa Masjid, which is completely not true.
The Al-Aqsa Mosque complex is located in Jerusalem also known as al-Quds or Bayt al-Muqaddas, the capital of Palestine.
Please see the photos and links to understand the different. We have an obligation as Muslims to represent the truth.
