Shaikh Muqbil ibn Haadi al-Waadi’ee rahimahullah said:
“What is placed on the breasts (i.e. a bra) then there is no harm with it inshallah and there is no problem in it. I do not know of a preventative for this…” [Ajwibatul-Waad’iee ‘an Asilatul Nisaaiyyah pg. 331]
The Shaikh was also asked:
Question: What they [the women] wear of upon the breasts [i.e. the bra]. What is the ruling on it?
Shaikh: Why do they wear it?
Questioner: They fear this breasts will droop/hang
Shaikh: There is no harm in this inshallah. There is nothing [wrong] in it.
Interjector: Some women wear it in order to deceive.
Inerjector: In order to raise her breasts.
Interjector: This because some women have small breasts so they wear this bra to enlarge it. Some have large breasts so it holds them and raises them?
Shaikh: If it holds them or raises them, then is not harm inshallah.
Questioner: The speech is pertaining to the husband oh Shaikh. The speech is pertaining to a [wife] in front of a husband.
Shaikh: In front of a husband. I do not know of a preventative for this.
Questioner: A woman also places a barrier between her breast and clothing fearing that breast milk will come on the clothing or the likes.
Shaikh: I do not know of a preventative for this”.
