When contacted by the News, the store's assistant manager, who refused to give her name, said: "It is true that Muslims can't sell cigarettes - I used to be Jehovah's Witness and I wouldn't on religious grounds either."To add insult to injury, this anti-cigarette-selling Muslim is making it up as she goes along.
She said the customer should have realised the shop assistant was a Muslim, and would not sell her tobacco, because she was "sitting there in her full robes".
Asked why the store had someone who would not sell tobacco working behind the till, she said: "It is against the law to discriminate against people on religious grounds".
Asim Mumtaz, president of the Ahmadiyya Muslim Association in Cambridge, said: "I don't think there is any basis for refusing to sell cigarettes.
"Islam, like most religions, is against anything that injures health or the body, but there is no ban on cigarettes or on smoking.
Aren't these the people, after all, who gave us the hookah?
