A doctor convicted of conspiring to give health support to al-Qaeda fighters received a sentence of 25 years in prison on Wednesday.

Moreover, Rafiq Sabir, 53, of Boca Raton, Fla., seemed to have no regrets after he had been convicted in May for conspiring to provide material support to terrorist, according to US District Judge Loretta A. Preska, Reuters reports.

The doctor agreed to treat injured al-Qaeda members so they could return to Iraq and continue fighting against the Americans.

There was "no reason to believe that this defendant has abandoned any criminal intentions. Terrorists cannot succeed without the treatment of their wounded,” the judge said.

Sabir, a strict Muslim raised in New York, pleaded “completely innocent” in front of a crowded courtroom, minutes before the sentence was given. He stated that Tarik Shah, a martial arts expert and jazz musician, had misled him.

"I had no clue I was being asked to treat al Qaeda members. I am an extremely gullible man who made some foolish mistakes in my life," Sabir said in front of the judge, according to Reuters.

On the other hand, Shah and two other men also charged in the case pleaded guilty to terrorism charges. Shah was sentenced to 15 years in prison in a deal with the government, for agreeing to help al-Qaeda fighters in hand-to-hand combat. A Brooklyn bookstore owner, who pleaded guilty, was sentenced to 13 years in prison, while a Washington, D.C., cab driver received 15 years in prison.
