Second Section – the Negative Commandments
76. It is a negative commandment "do not make your friend stumble over anything."
As it states in Vayikra (Leviticus) 19:14, "do not put a stumbling block in front of a blind man." This means to say, if he is 'blind' in a certain area and asks for advice, do not give him advice that is improper. This includes anything he may ask about: worldly matters or Torah matters. It is also forbidden to bring someone to him, to help him, or to cause him to come to another person in order to do a sin. It is also forbidden to bring a non-Jew to transgress a Torah law which he is required to be careful to observe (the seven Noahide laws).
This applies in all places and at all times, for men and for women.
