The Importance of Nationalism in Islam

Not all types of nationalism are haram rather if used properly any type of sentiment can be used for good and for bad. He's invoking who am i my grandfather was abdu mottalib now we all know in islam it doesn't matter who your father grandfather is. There's nothing wrong with invoking that for aitimate cause for a legitimate cause. As long as that pride is within the pride of islam it should never be more than the pride ofIslam after all.
