Is celebrating independence day allowed islamically ?

I thought we are supposed to do exactly that :confused:

Observing independence day of a country ( even muslim) has no place in

1.Islamic theology
2. Islamic tradition

Creation of different Muslim countries and nationalism has no place in islam.
there was a single islamic empire for some 1300 year, even though i dont think anyone ever celebrated it independence day.

I quote Dr. Muhammad Iqbal herewith as he understood the concept :

In taza khudao.n main BaRa sab se watan hai
Ju parahan iska hai, wo mazhab ka kafan hai
