Wearing perfume when going out to hospitals, school or to visit relatives

It is permissible for her to wear perfume
if she is going out to a women’s gathering and she will not pass by
any men en route. But going out wearing perfume to market-places where
there are men is not permitted, because the Prophet

(peace and blessings of Allaah be upon him) said: “Any woman who has
applied bukhoor (incense) should not attend ‘Ishaa’ (prayers) with us.”
And there are other ahaadeeth concerning this matter.  That is
because if she goes out wearing perfume to places where men walk or
places where men gather such as the mosques, this causes temptation
to them. She must also cover herself and avoid wanton display (tabarruj),
because Allaah says (interpretation of the meaning): 

“And stay in your houses, and do not
display yourselves like that of the times of ignorance”

[al-Ahzaab 33:33]

Tabarruj includes showing the sites of temptation and
beauty such as the face, head, etc.
