Is it permissible for a married woman to insert an IUD for contraception without her husband's knowledge, if he insists on her repeated pregnancies despite her physical and psychological exhaustion and her preoccupation with work?

It is permissible for a woman who is exhausted by closely spaced pregnancies to seek a permissible temporary contraceptive method to regain her health, and her husband should understand her situation. However, inserting an IUD is not permissible due to its inclusion of Sharia-related caveats. It would have been more appropriate for the woman to agree with her husband on a specific period for rest and recovery, and to take the legitimate means for that.
