Nowadays, men’s looking at women is considered wrong, but women don’t consider seeing men and meeting them as a sin although there is a danger of the doors of immodesty being opened with seeing non-Mahram males without a reason accepted by the Shariah. The Sahabah (companions) would consider this very wrong, as is reported about Hadhrat Ma’adh Bin Jabal (May Allah be well pleased with him):
Translation: When he came to his house, he saw his wife peeping out of a hole in the tent, as a reprimand, he slightly tapped her. (Al Tabaqat Ul Kubra Li Ibn Sa’ad, Ma’adh Bin Jabal)
