Why it is forbidden to look to a foreign woman's hair, arms or legs?

Well, Islam treats woman as a jewel that has to be dealt with carefully and respectfully ....... Not as goods or as a piece of merchandise that is exhibited on the windows of supermarkets or shops ...... Exhibiting what are good things of such pieces of merchandise and actually concealing what is bad ! ...... One look at the vogue of costumes .... You will see the woman's bodies are exhibited like merchandise......

If you have a favorite jewel or a precious thing ....... Do you have to exhibit it to the people unprotected ..... Do treasures, say the royal crown of the UK for example ..... exhibited to the people unprotected and unguarded ? ....... the answer is actually is a big NO ..... So, Muslim woman, a jewel and a queen is never exhibited ..... She is protected and guarded by protective clothes that keeps her beauty and charm for her husband only .... Not for any passer-by who may look at her with lust and penetrating her clothes with his eyes

That is why a Muslim woman is ordered to wear a Hijab that conceals her beauty and charm ..... and a Muslim man is ordered not to look for foreign women ..... So that he may not look with other women with lust or look to what makes him imagine something lusty or unfavourable ..... And that is why the number of rape accidents and illegitimate children in the Muslim world is negligible .
