The UK-based Syrian Observatory or Human Rights (SOHR) said commanders had also drawn up a list of rules detailing how injured players can be compensated by their opponents under Sharia law, Independent UK reports.
Monitors reported that the so-called Islamic State had declared the implementation of international football rules “illegitimate” in Deir ez-Zor governorate.
Local sources told SOHR militants told football organisers referees would be banned because their decisions “do not judge according to what Allah has revealed” and are “a violation of Allah’s command and the Sunnah”.
A system of “Qisas” for injured footballers was also brought in, referring to the retributive justice system enacted under Sharia law, where victims can claim compensation or exact revenge.
The reported ban was decided by courts established by Isis to rule on issues of Islamic jurisprudence according to its extremist ideology.
It came before the start of league matches due to take place between teams in the group’s territory around Deir ez-Zor city.
