The father of a dead Indian man who pledged allegiance to ISIS and was allegedly involved in a train attack that left 10 people injured on Tuesday has refused to accept his body — saying a “traitor” is no son to him.

“One who indulges in anti-national activities can’t be my son,” explained Sartaj, dad of Saifullah, who was shot dead by police near the Indian city of Lucknow, a day after the terror strike.

“It’s that straightforward,” he told The Times of India on Wednesday. “We will absolutely not accept a traitor’s body. He has brought infamy not only to us but to the whole nation, therefore we will not accept his body for last rites.”

Saifullah, who was said to be in his 20s, was allegedly part of a newly-formed ISIS cell in Kanpur — which was made up of at least nine members, including two of his cousins, NDTV reports.

On Tuesday, the group unleashed the first-ever ISIS attack in India — injuring 10 people aboard a passenger train in Madhya Pradesh with a low-intensity bomb, according to TOI.

While eight of the terrorists who were allegedly involved in the strike were arrested on Tuesday following the blast, Saifullah managed to evade police for a few hours and eventually found a house to hole up in.

As authorities moved in to arrest the young man on Wednesday morning, he reportedly opened fire on officers — causing them to shoot and kill him after a 12-hour stand-off.

Saifullah, who was a commerce graduate of Manohar Lal College in Jajmau, had called his father the day before the train attack to tell him he was leaving the country.

“On Monday, I got a call from Saifullah, who told me that he had got a visa to visit Saudi (Arabia) and he was preparing to go there,” Sartaj said. “I told him go ahead.”

The disgusted dad told TOI that Saifullah had fled his home about two-and-a-half months ago after he beat him up for not having a job, according to the newspaper.

His son reportedly claimed at the time that he wanted to work as a driver.

Sartaj said Saifullah’s sister, Zareen, was also horrified to hear of his alleged actions.

“Look, someone who’s a traitor cannot be our son,” he fumed. “We are Indians, we were born here, our forefathers were born here and anyone who’s a traitor can’t be a son or any relation of ours.”
