Brothers are sisters, The Muslim flag had been black from the Prophet till dynasties used black flag such as Abbasids and Ummayads, etc. The nationalist flags , the flags of Taguweet such as Lebanon, Jordan and Pakistan are all void in front of flag flag of Prophet. The black standard had been a symbol of pride and rule in Islamic world. After the colonization of Muslim world was dying the British kuffars divided us in different lands and flags draw the skies-picot border the Durand line, borders of Pakistan, etc. They tend to imprison us in these borders making us nationalistic and loyal to our people and flag. 

Narrated Al-Bara' ibn Azib:
Yunus ibn Ubayd, client of Muhammad ibn al-Qasim, said that Muhammad ibn al-Qasim sent to al-Bara' ibn Azib to ask him about the standard of the Messenger of Allah (ﷺ). He said: It was BLACK, and square, being made of a woollen rug.   :

What Jahaliya is this, getting up for a national anthem of country and respecting flags of your nation rather then advocating and calling for the use of Prophet's flag, the Sunnah flag. Calling yourself "Proud Pakistani" , "Proud Syrian" . Did Prophet PBUH ever said "Proud Arab". Did he called to tribalism and got angry for tribalism. Did he favored his tribe Banu Hashim against others? No brothers rather Prophet PBUH said 

It was narrated that Jundab bin 'Abdullah said:"The Messenger of Allah [SAW] said: 'Whoever fights for a cause that is not clear, advocating tribalism, getting angry for the sake of tribalism, then he has died a death of Jahiliyyah.'"

Prophet said that whoever dies for nationalism, advocating it and getting angry for it died a death of Jahaliyya. Ask your self do you get if somebody abuse the land of Pakistan, or step on its flag, do you dislike it? Why brother, do you get angry for a banner of folly? Do you want to die a death of Jahaliya or a death upon Islam? 

Even playing national anthem and songs are haraam as they contain music so only an ignorant man would get angry for nationalism and advocate it instead of the black flag of Prophet. 

Allaah says (interpretation of the meaning): “And stand before Allaah with obedience” [al-Baqarah 2:238]. 

So my brothers repent to Allah from advocating nationalism and promoting your flags and nations, remember Muslim Ummah have one flag (black flag), one land and one leader.
