In the video shared by Mouaz Al-Nass, an Islamic musician of Syrian descent, Al-Nass can be seen chanting the adhan in the typical rhythmical manner inside the palace.
According to Al-Arabiya, the palace, which was built by Muslim rulers in the 1330s, had not witnessed the Islamic call to prayer in nearly five centuries.
Al-Nass recited the full Islamic call to prayer in the palace and fortress complex, which is located in Granada, taking spectators aback with his performance, with many of them reaching for their phones to take photos and videos.
Why? He felt that the walls had missed "hearing the call to Allah," Al-Nass told Ilmfeed.
Born in Jeddah, Al-Nass is a singer and drummer who specializes in Islamic music and holds a university degree in Management Information Systems from Syria.
Alhambra Palace, known as Qalat Al-Hamra in Arabic in reference to its reddish walls, was built as a military fortress by Muslim rulers of Granada towards the end of the Muslim rule of Spain in the 1330s.
When Granada came under Christian rule in the 1490s, the palace "was known at the time to have been a final place of refuge for artists and intellectuals," Al-Arabiya reports.
The palace was Al-Andalusia's last-standing stronghold before falling to the Spanish Catholic army, after which Muslims were forced to convert to Christianity or face torture.
Since Al-Nass first posted his video last week, it has garnered over one million views and over 25,000 shares on Facebook, with comments pouring in.
