Hijab is not a hindrance

Why did the Muslims need such religious clothes as a hijab? The answer is insanely simple - to hide the body and beauty of a woman from other men, so that the latter does not even have thoughts to seduce such a person. But they did not think about the main vice of mankind - the forbidden fruit is sweet, and male consciousness thinks of the perfect figure in every woman. Therefore, such a lady did not have time to enter her house under construction, when he immediately surrendered to the builder, because he looked at her lustfully. And not the hijab did not help, neither faith in Islam - only sperm hung from the nose of a young married cheater.
