Most of the people didn't know what is Nationalism or is it Halal or Haram in Islam. Here i explain more detail about Nationalism in Islam. Hope it help us to understand more about it, jihad for Islam and Allah swt not for Nationalism.

Nationalism is a concept alien to Islam because it calls for unity based onfamily and tribalistic ties, whereas Islam binds people together on the`Aqeedah, that is belief in Allah (swt) and His Messenger (saw). Islam calls for the ideological bond.

Grouping the Muslims on tribalistic lines is clearly forbidden. It is narrated by Abu Da'wud that the Messenger of Allah (saw) said, "He is not one us who calls for `Asabiyyah, (nationalism/tribalism) or whofights for `Asabiyyah or who dies for `Asabiyyah." And in another Hadith, the Messenger of Allah (saaw) referring tonationalism, racism, and patriotism said: "Leave it, it is rotten." [Muslim and Bukhari] and in the Hadith recorded in Mishkat al-Masabith, the Messenger of Allah (saaw) said, "He who calls for `Asabiyyah is as if he bit his father's genitals".

Also, the Messenger of Allah (saw) said, narrated by At-Tirmidhi and AbuDawud, "There are indeed people who boast of their dead ancestors; but in the sightof Allah they are more contemptible than the black beetle that rolls a pieceof dung with its nose. Behold, Allah has removed from you the arrogance ofthe Time of Jahiliyyah (Ignorance) with its boast of ancestral glories. Manis but an Allah-fearing believer or an unfortunate sinner. All people are the children of Adam, and Adam was created out of dust."

Also, the Messenger of Allah (saaw) said,"Undoubtedly Allah has removed from you the pride of arrogance of the age ofJahilliyah (ignorance) and the glorification of ancestors. Now people are oftwo kinds. Either believers who are aware or transgressors who do wrong. Youare all the children of Adam and Adam was made of clay. People should giveup their pride in nations because that is a coal from the coals ofHell-fire. If they do not give this up Allah (swt) will consider them lowerthan the lowly worm which pushes itself through Khara (dung)." [Abu Dawudand Tirmidhi]
