Indeed al-Madeenah has changed tremendously since then
My family member who lives in al-Madeenah told me that now what used to be the entire city is now included in the Haram Vicinity
Correct abbreviation is al-Madeenah
Since medina means city
And al-Madeenah means
The City
The City meaning
The City of the Prophet (S)
Full name in Arabic
Madeenat ur Rasool (S)
Peace for Everyone !
