The ruling on looking at people's private parts in public places

Question:
The issue is: does looking at people's private parts in public places, such as the open road and the like, fall under the ruling for the one who is fasting?

Answer:
This is forbidden; it is not permissible to look at people's private parts. However, do not call it the ruling for the one who is fasting, because this is exposed and apparent. It is obligatory for him to cover his private parts and cover his daughters. But if it is exposed, whether it is him or the women, it is not permissible for him to look at it; doing so is forbidden and he commits a sin. Allah, Glorified and Exalted is He, says: .
The Messenger (peace and blessings be upon him) said: Does not the person know that he is looking at what Allah has forbidden? But if what Allah has forbidden is hidden, and he comes upon it while it is hidden in his house or in his inheritance, that is the one who is fasting. As for if it is exposed and he looks at it, this is forbidden and he commits a sin. Yes.
