What is the ruling on a woman perfuming herself and using incense for her husband in her home in the presence of her husband's brothers, and what is the ruling if they smell her scent?

For a woman to beautify herself with perfume and clothes for her husband is مطلوب (desirable), but for his brothers, it is haram (forbidden) because they are ajnab (non-mahram) to her. She must be careful not to appear before them or to perfume herself in their presence. Her adornment and perfuming should be for her husband in her room only. If they smell her fragrance unintentionally on her part, there is no blame upon her.
