What is the ruling if a woman finds that she is pregnant during her iddah period? Does the iddah continue on with the 3 months rule or does it continue until the pregnancy is complete?
All the scholars agree that the iddah of a divorced woman that is pregnant ends when she gives birth because Allah says in the Quran:
“And for those who are pregnant (whether they are divorced or their husbands are dead), their ‘Iddah (prescribed period) is until they lay down their burden”
