I am a sunni but my father was a shia by birth. Can I marry a sunni girl. Some imam said that if my father is a shia then nikah will be invalid

A`uuthu Billaah for that saying. Brother I think the imam is afraid you are making taqiyah, and are not sincere in your claim. That`s very difficult and sad. It cannot be true anyway, because if the religion of a preson was to be determined according to their parents, then our beloved Prophets of Allaah Ibraahiim -`***- and MuHammad -sAa`ws- would be both mushriks. So you can tell that Abu Bakr from Finland asked you to tell him this and make taubah for his ignorant claim, if it is true you have understood him correctly.

Forgive my spelling mistakes, because it makes me angry someone lies about Deen.

The Koran condemns "schismatics" in no uncertain terms, who are the ones going on with "Sunni" this or "Shia" that.. real Moslems cast truth at falsehood, according to the following stricture in the Koran.

In the name of Allah, the Beneficent, the Merciful
Cast truth against falsehood
The Koran: Chapter 21, verse 18

And despise schismatics, and false Moslems who fail to "cast truth" about equally.. 60,000 or so Jews failed to turn up for work at the WTC, 11 September 2001, whence allegedly hijacked aircraft, were flown into the World Trade Center in New York.

In an attack blamed on Arabs, which became the impetus for the current wars against all and sundry, in the name of the War on Terror.. Mossad agents filming the drama amid “evident Jewbilation,” and Put Options on airline stocks, that made hundreds of millions traced to Mossad HQ in Yisrael, says Jews did it.

I similarly castigate all Persian, Iranian, Middle Eastern, Indonesian, and the Atalanta and Chicago False Moslem congregations in the United States, as unbelievers of the worst kind, for similarly failing to "cast truth," in a matter of such vital importance as illegal war!

Agriculture, writing, and the domestication of animals, all originated in the Tigris Euphrates region called Iraq, the tribes that have been located there since the time of Adam, are the Sunni.

The Shia are every one else, the Sunni are often don't do the manual chores, so they have been bringing in workers from other places for centuries, these workers do not usually attend Sunni mosques, which are most often built and maintained by a single extended family.

They usually attend to their religious affairs, in Mosques that are located in working class areas of the city, that have become known as Shia Mosques.

At no time has war or conflict between the two sectors of society, been permitted, either under secular law, or within the strictures of Islam, and all parties are aware, that murder is met with speedy and deadly retaliation, according to the instruction in the Koran.
