Police launched a murder investigation after discovering a man shot dead in a car in Wembley.
Officers have not officially identified the victim but he has been named locally as Abdul Hadi Arwani.
Known for his opposition of Syrian President Bashar al-Assad, Abdul was considered an authority on Islamic marriage contracts and divorce law.
Detectives continue to appeal for anyone with any information in connection with the case to get in touch.
