Question: What is your advice for the one living in the lands of the disbelievers in regards to dealing with women?
Answer: “Dealing with women, as is well-known, is by a man keeping away from them, not free-mixing with them, and not approaching them. If he is forced to address one of them, like a female employee at the airport or in something [i.e. a situation] that he is going through, then he deals with her according to the necessary limits without looking at her or indulging in speech with her. He only talks to her according to the need he has. It is not allowed to shake the hand of women and not to look at them. This is the same in the lands of the disbelievers and the land of the Muslims”.
