One cannot deny the feeling of love for one’s family, tribe, home country, etc. This feeling is not prohibited. But it has to be within the parameters of Islamic principles and Shari`ah objectives. All sorts of bigotry and fanaticism based on such feelings are prohibited. The bond of Islam has priority over all other kinds of relations.

The Messenger of Allah (peace and blessings be upon him) is reported to have said, “Allah has removed the pride of Jahiliyyah from you and boasting about lineage. [A person is] either a pious believer or a wicked sinner. People are the children of Adam, and Adam is from earth.”

So a Muslim, for example, may not hate or begrudge, let alone to fight, another Muslim only because he belongs to another country or tribe.

As for the national anthem, it has to be free from any words or expressions that contradict the abovementioned principle. If so, it is permissible to sing it if there is no musical instruments used.

The majority of scholars prohibit the use of musical instruments in all cases. However, according to a group of scholars, it is permissible to use musical instrument in such cases.

Allah Almighty knows best.
