Praise be to Allaah.
It is permissible to use condoms so long as this does not cause any harm and so long as both husband and wife consent to their use, because this is similar to ‘azl (coitus interruptus or “withdrawal”). But it reduces the sensation of pleasure, which is the right of both partners, and reduces the chance of conception, which is also the right of both partners. Neither one of them is allowed to deprive the other of these rights. (For more information, see Question #1100 and 566). And Allaah is the Source of strength.
