Muhyyee-ud-din Abdul-Rahman, a West Philadelphia man who was a teenager when he first came under scrutiny, was sentenced Thursday to 20 to 40 months in state prison and six years of probation after a jury found he had tried to build bombs in support of Syrian extremist groups. Because he has already logged roughly 34 months behind bars, the judge’s decision leaves him with at most about six more months in custody. The relatively short term drew sharp pushback from the district attorney’s office, which argued the punishment does not match the gravity of his conduct.
As reported by The Philadelphia Inquirer, a jury in September convicted the now 20-year-old of attempting to possess a weapon of mass destruction and related offenses. Jurors acquitted him of the most serious WMD possession charge, and Common Pleas Court Judge Michele Hangley later threw out a conspiracy count. Hangley imposed the 20-to-40-month term under state sentencing guidelines that prosecutors say are far more forgiving than federal terrorism benchmarks, and the district attorney’s office has said it is considering an appeal.
Prosecutors Say He Tested Explosives And Researched Targets
According to the Philadelphia District Attorney's Office, the case began in 2023 after the FBI’s Joint Terrorism Task Force flagged Abdul-Rahman for communicating online with accounts linked to Katibat al Tawhid wal Jihad (KTJ). Investigators said surveillance and subsequent searches turned up wires, chemicals and other components associated with homemade explosives. Agents also reported watching him purchase muriatic acid at a Lowe’s, describing it as a key ingredient in a volatile mixture they identified as TATP.
Prosecutors further pointed to a trail of internet searches, including queries about parade routes, trash-can bombs and nuclear power plants, which they characterized as “target and tactic” research. Those digital breadcrumbs, along with the recovered materials, were cited as evidence that the plot posed a credible threat before authorities stepped in.
DA Blasts Sentence As Too Soft
District Attorney Larry Krasner said he was “deeply concerned” that the punishment fell short of reflecting the danger prosecutors say Abdul-Rahman presented and noted that his office had pushed for at least a decade behind bars, according to KYW Newsradio. “If you sense a certain level of concern and outrage on my part, it is real,” Krasner told reporters, criticizing the gap between state sentencing rules and federal standards for terrorism-related conduct. Prosecutors said the term imposed was out of step with the threats they believe were averted.
Defense attorney Donald Chisholm had urged the court to show leniency, arguing his client was an impressionable teen swept up in extremist online propaganda who has since grown up in custody. Abdul-Rahman told the judge that he has rejected the radical ideology he once embraced, and Chisholm said the defendant was “not fully matured,” as reported by The Philadelphia Inquirer. His father, criminal-defense lawyer Qawi Abdul-Rahman, is a familiar figure in Philadelphia’s legal community, adding another layer of scrutiny to the already high-profile case.
What Comes Next
The district attorney’s office and the FBI have framed the prosecution as a local test case in handling matters that often land in federal court, arguing the investigation cut off what they described as a credible regional threat, according to the Philadelphia District Attorney's Office. Abdul-Rahman was arrested on August 11, 2023, and his substantial time already served means Judge Hangley’s sentence leaves limited additional prison time before he transitions fully to community supervision.
Prosecutors say they are still deciding whether to appeal, a move that could trigger a broader fight over whether the sentence adequately addresses public-safety concerns. In West Philadelphia, the case has sharpened anxieties about how quickly online radicalization can escalate and how state sentencing ranges stack up against federal terrorism penalties. For now, Abdul-Rahman remains under the court’s eye, facing years of probation even as his prison term winds down.
