Is it permissible, from a Sharia perspective, to use the modern method of contraception that involves inserting a rubber ring containing hormones, which prevents the fertilized egg from attaching to the uterine wall, as opposed to other methods that prevent ovulation?

The contraceptive rings function similarly to pills in preventing ovulation and attachment to the uterine wall. This transparent vaginal ring, made of plastic, is inserted for three weeks and releases a hormonal substance that prevents ovulation, makes the uterus unsuitable for egg implantation, and obstructs the passage of sperm. It resembles the IUD in its mechanism, as it prevents the fertilized egg from settling in the uterus.

Preventing the egg from settling in the uterus is not considered an abortion. Abortion pertains to the sperm that has settled in the uterus, and some jurists have permitted the abortion of the sperm before forty days. The "Permanent Committee" has permitted contraception or its delay due to necessity or benefit, by analogy with the permissibility of coitus interruptus (azl) and the permissibility of expelling the sperm before forty days.
