ISIS joined Donald Trump on Sunday in dishonoring the sacrifice of U.S. Army Capt. Humayun Khan.

The newest issue of the so-called Islamic State’s propaganda magazine Dabiq said the Muslim war hero died as an “apostate” when he was killed by a car bomb in Iraq in 2004 after ordering soldiers under his command to stand back as he moved foward to investigate the vehicle.

Khan was posthumously awarded the Bronze Star and Purple Heart and is buried at Arlington National Cemetery. ISIS published a picture of his headstone and captioned it, “Beware of dying as an apostate.”

The terrorist group calls all Muslims who don’t adhere to its narrow ideology apostates and reserves particular ire for those who live and participate in Western democracies.

Like ISIS, Trump made the issue Islam instead of Khan.

And on the same day that ISIS smeared the son’s name, Trump excoriated Khan’s parents, who addressed their son’s sacrifice and Trump’s anti-Muslim racism at the Democratic National Convention.

“If it was up to Donald Trump, he never would have been in America,” Khizr Khan, the soldier’s father, said. “He vows to build walls, and ban us from this country.”

Trump first responded in a statement where he said the Khans had “no right” to criticize him.

“Captain Humayun Khan was a hero to our country and we should honor all who have made the ultimate sacrifice to keep our country safe,” he said. “While I feel deeply for the loss of his son, Mr. Khan, who has never met me, has no right to stand in front of millions of people and claim I have never read the Constitution, which is false, and say many other inaccurate things.”

Khizr Khan immediately struck back, calling the statement “faked empathy” that is “typical for a person without a soul.”

Not content with insulting the father of a slain soldier, Trump bashed Capt. Khan’s mother (who last spoke to him on Mother’s Day 2004), intimating that she was barred from speaking by her husband at the DNC because she is Muslim.

“She had nothing to say. She probably—maybe she wasn’t allowed to have anything to say,” Trump told George Stephanopolous in an interview airing Sunday. (The Republican nominee added that Khizr Khan was “very emotional” but a “nice guy.”)

Ghazala Khan responded directly to Trump in a Washington Post op-ed on Sunday, saying he is “ignorant” about Islam and “doesn’t know what the word sacrifice means.”

Trump belittled that claim when Khizr Khan made it at the DNC.

“Did Hillary’s script writer write it?” Trump asked in the Stephanopolous interview, which was taped on Friday.

In fact, Khan spoke extemporaneously.

Then Trump continued to claim he has a made a “lot of sacrifices” by creating jobs.

The same issue of Dabiq apparently took a jab at Hillary Clinton while saying nothing about Trump. The magazine rails about the “extinction” of Western women because of the West’s war on human nature, which dictates that “woman does not imitate man.”

“For this reason, when the daughter of a Persian king became ruler of Persia, the Prophet said, ‘A people who give their authority to a woman will never prosper,’” it said.
