In secular countries, the Pledge of Allegiance is to the flag of the country. How do Mus-lims look at such a pledge?

Any person who makes his Pledge of Allegiance to the flag of his country,  is legally responsible to defend that country according to what the political leaders decide. The leaders may decide to invade other countries and commit various types of injustices, atrocities, and crime. A Muslim’s loyalty is to God. He will never obey political leaders unless they themselves obey God. Partaking in unjust wars is amongst greatest of crimes.   Therefore, the masses as well as the leaders should make a Pledge of Allegiance to God, the Creator of the whole universe.
