What is the ruling on looking at naked Western girls in widely circulated e-mails, and does this fall under the warning mentioned in the hadith: "Whoever pursues the 'awrah (private faults/imperfections) of his brother, Allah will pursue his 'awrah until He exposes him in his own house"?

It is forbidden to look at naked girls from the West or elsewhere, whether in emails or other media and communication channels. The aforementioned Hadith is cited by scholars to attest to the prohibition of spying and seeking out the private matters of Muslims. It is not cited to prohibit looking at pictures of naked girls, as this is prohibited by verses [of the Quran] and Hadiths. As for citing it to permit looking at pictures of non-Muslim girls, this citation is out of place, for the prohibition of looking at a woman’s nakedness is general and includes both Muslim and non-Muslim women.
