A Saturday night spat among teenage girls at a Brooklyn mosque only got worse after their parents stepped in, and the mother of one girl stabbed the father of another, police said.

Jacquelyn Binyon, 55, of Philadelphia, was charged with stabbing a 46-year-old man in the neck at Al Farooq Mosque at Boerum Hill, police said. The victim, who was not identified, was taken to Bellevue Hospital, where he was listed in stable condition.

The mosque’s president, 66-year-old Amin Awad, said the two girls had been arguing for days over some pocket change.

At 5:25 p.m., the girls got into a heated argument following prayer services in the women’s worship room. The victim, who is married and has three children, arrived at the mosque to pick up his wife and daughter. The victim was trying to remove his daughter from the fracas when Ms. Binyon took out a paring knife and stabbed him in the left side of the neck and slashed him on the right hand, according to police and Mr. Awad.

Ms. Binyon, who had began worshipping at the mosque 10 days before to the stabbing, was charged with first-degree assault and criminal possession of a weapon.

“We don’t know much about her,” said one worshipper, 45-year-old Saleh Altaheri. “I think she has mental problems, to take a knife like that and stab someone. It’s really a shock. You come to a place of prayer because you feel safe.”

The Al Farooq Mosque, a community mosque known to have raised money for Al Qaeda, is located on a stretch of Atlantic Avenue lined with shops selling Muslim and Middle Eastern literature.
