Many independent Muslim schools in England are under threat of closure, according to the Association of Muslim Schools (AMS).
The organisation, which represents almost 100 independent Islamic institutions, said many could not afford to stay open.
Most schools use fees and donations to cover costs and need about £2000 per pupil per year to stay afloat.
But the recession has seen donations fall and parents unable to pay fees.
The threat applies to "almost all" of the 130 Muslim faith schools in England, according to the association.
