The mother of San Bernardino terrorist Syed Farook has been pictured by DailyMailTV just days after the four-year anniversary of the massacre by her son and her daughter-in-law at a Christmas party.

Rafia Farook, 66, shared a home in Redlands, California, with her son and his ISIS-following wife Tashfeen Malik, and their baby daughter.

But she told investigators that she had no idea he was plotting a terrorist attack – even though the couple built some of the small bombs later used in the December 2, 2015 massacre at the home.

The spree killed 14 and injured 22, almost all of them colleagues of Farook's at the San Bernardino Department of Public Health.

Farook, 32, and Pakistan-born Malik, 28, were gunned down by cops as they attempted to flee the scene in a rented Ford Expedition SUV.

Exclusive DailyMailTV photos show Rafia Farook arriving at a local mosque on Friday in the rain.

She, her other son Syed Raheel, 34, and her husband Syed Sr., 70, were there for afternoon prayers.

Approached by DailyMailTV, Rafia refused to discuss her mass murderer son but said she was doing 'OK' four years on.

Rafia, who now lives with Syed Raheel in Corona, California, has always insisted that she did not notice Farook and Malik's increasing radicalization or have any idea of their plans, and was caring for their baby daughter on the day of the atrocity.

The little girl, who was six months old when she was orphaned, was removed by Child Protective Services immediately after the shooting and is now understood to be living with a foster family.

Syed Raheel also refused to comment on the slaughter when spoken to by DailyMailTV but did say that the family is now trying to move on.

That would appear to be a forlorn hope with Syed Raheel, Tatiana and Rafia herself all facing court next year.

Rafia is battling the Justice Department over Farook's $280,000 life insurance policy of which she was the primary beneficiary.

Insurers Minnesota Life Insurance paid out shortly after the attack but the funds were held by court after the Justice Department attempted to have the cash seized as proceeds of crime.

Rafia is continuing to fight attempts by the federal government to retain the payout.

She says that because she did not know her son was going to commit an act of terror, there is no reason for the money not to be paid.

Rafia's other son Syed Raheel and his Russian wife Tatiana will appear in court next year to be sentenced after they pleaded guilty to conspiracy to commit immigration fraud

Syed Raheel will be sentenced on May 18 after pleading guilty to one count of conspiracy to commit immigration fraud in January 2017. Wife Tatiana was convicted of the same crime and is due to be sentenced on February 10

Meanwhile, Syed Raheel will be sentenced on May 18 after pleading guilty to one count of conspiracy to commit immigration fraud in January 2017.

He faces a maximum sentence of five years in jail and a $250,000 fine.

Wife Tatiana was convicted of the same crime and is due to be sentenced on February 10.

The immigration convictions relate to a sham marriage arranged by Syed Raheel for his wife's sister Mariyah with terror accomplice Enrique Marquez Jr., 27.

Marquez Jr. is currently serving 25 years in federal prison after admitting to purchasing guns that were later used in the attack.

According to court papers seen by DailyMailTV, Marquez, an Islamic convert and Mariyah - who has two children with boyfriend Oscar Romero, 37 - entered into a fake marriage in November 2014.

Syed Raheel and Tatiana later signed affidavits claiming to have been present at the wedding – despite no such event taking place.

Tatiana arrived in the U.S. in 2006 and was initially married to an older man, Peter Gigliotti, 50, of Portland, Oregon.

Although it is unclear how she met Navy veteran Syed Raheel, by 2011, she had divorced Gigliotti and in August that year, the pair married.

Sister Mariyah, who lives in Ontario, California, began a relationship with Romero shortly after arriving on a three-month tourist visa in 2009.

When Mariyah's visa expired, she arranged with her sister and brother-in-law to marry Marquez Jr, who is a childhood friend of Farook's and lived in the same street.

Marquez Jr. admitted the sham relationship while being questioned by FBI agents after the 2015 shooting, telling them how his fake bride paid him $200 a month to keep up the charade.

He is currently attempting to overturn his guilty plea and will return to court in January.

Mariyah is due to be sentenced on March 9 after admitting one count of conspiracy, another of perjury and two counts of making false statements. She also faces a deportation hearing.

Rafia's case is due to be decided once sentencing on the immigration fraud cases is complete.
