The Reason behind the Waiting Period
Question :

Seeing that the significance behind the iddah period is so that the father can be identified adequately if the woman becomes pregnant, and contraception almost eliminates the chances of pregnancy, is there any need of the iddah period when using contraception?

Answer :

The reason behind the waiting period is not necessarily identifying the father if the woman is pregnant. If this was the reason, then it would have been sufficient for Almighty Allah the Divine Legislator to consider one menstrual cycle as a waiting period and not any longer duration. Almighty Allah knows the actual reason behind such legislation.
Therefore, the iddah must be observed even if contraception was used.
