Bitcoin is acceptable in the eyes of Allah, a mosque has declared, as it becomes the first in the UK to accept cryptocurrency donations.
Religious advisers at the Masjid Ramadan in Dalston, east London, have said the currency is halal if it is "transacted in a lawful manner".
There has been significant debate about cryptocurrency in the Muslim world, with figures including the Mufti of Egypt suggesting it is haram, or forbidden, because it is used by some for illegal activity.
Because of its anonymous nature bitcoin has become associated with buying drugs and other unlawful items online.
But the mosque has declared that Muslims can use it for their Ramadan donation, known as zakat.
