A new Fatwa in the United Arab Emirates forbids as desecration the use of Qur'anic verses as ring tones. The justification is that the telephone may ring in inappropriate places where such verses should not be heard and that if you answer your cell in the middle of the verse, people will not hear the whole verse which may distort its meaning.
Don't these concerns apply to playing Qur'anic verses in other public places? In a taxi, in a cassette store, in a coffee shop, on a university campus? on Radio, on TV?
Anyway, I had no idea people did that! I will never catch up with all these high tech gadgets! How frustrating.
