In Islam dogs are regarded as unclean and are not allowed in mosques.
However, the Muslim Law (Shari'ah) Council UK has now issued a fatwa which allows guide dogs inside mosques but not into prayer rooms.
The Guide Dogs for the Blind Association and the Muslim Council of Britain worked together to support Mohammed Abraar Khatri's request.
Guide Dogs for the Blind said it was "a massive step forward for other blind and partially-sighted Muslims".
An association spokesman said: "It is also hoped that mosque leaders both in the UK and internationally will now make similar adjustments to enable Muslim guide dog owners to enter their mosque."
Mr Khatri, who owns a guide dog called Vargo, said the religious authorities felt they had a duty to help him.
