Does wudu' become invalid if a woman touches a non-mahram man?

Touching non-mahram people after performing wudu'?
Answer: This requires a detailed explanation: A woman is not permitted to touch a non-mahram man. However, if she touches his hand or his foot, her wudu' does not become invalid. Likewise, if she touches her brother's hand, her father's hand, her uncle's hand, or kisses his head, his nose, or something similar, her wudu' does not become invalid, as previously mentioned.
As for the non-mahram: A non-mahram man is not a mahram to her. She must not touch his hand or anything else, she must not shake his hand, and she must not touch any part of his body. He must not touch her either. She should only greet him from a distance without touching, saying, "How are you, so-and-so?" or "Peace be upon you," or "How are your children?" or "How is your family?" or the like, without shaking hands, without uncovering, and without touching. Rather, she should veil herself from him, keeping her face, hair, and body covered. She greets him with words and asks about his family with words. He likewise asks her without touching. She does not shake his hand, he does not touch her hand, she does not touch his hand, and so on. Yes.
