No woman should mourn for a dead person for more than three days except for a husband, in which case the period of mourning is four months and ten days.

In case of first and second divorce, if you want to be intimate with your wife during ‘iddah, according to some scholars this means that you have taken her back and her ‘iddah is over. Other scholars say that he should say words that indicate that he has taken her back (e.g., “I take you back” or “I take so-and-so back”) before he has intercourse with her, and that there should be two Muslim witnesses to these words. The second opinion is the soundest course to take.
