Deoband seminary issues fatwa against jeans, tight-fitting clothes and contraceptives .. and by extension, I assume tight-fitting contraceptives too:

Islamic seminary Darul Uloom Deoband has said that wearing jeans or other tight-fitting clothes is not appropriate as per religious beliefs.

In another controversial observation, it said a couple should first seek the opinion of a ‘hakim’ or Unani practitioner before resorting to use contraceptives if needed for medical reasons.

Wise men of the seminary: Please accept our thanks.
