Wannabe ISIS inmate allegedly told prison guard ‘I hope you die’ after stabbing

A Queens man awaiting sentencing for his failed attempts to join the Islamic State is facing new charges for gleefully stabbing a prison guard — and then praying for his jailor’s death.

Ali Saleh was slapped Wednesday with new charges for allegedly knifing a correctional officer at Brooklyn’s Metropolitan Detention Center on July 13, according to court filings and a law enforcement source.

The unnamed guard told prosecutors that Saleh, smiling, allegedly said, “I hope you die” after he’d plunged the blade into the man’s body.
