Is there a trial (fitnah) in the divorced woman remaining in her husband's house?

Question : What trial is this?

Answer : A liar. If he has intercourse with her for an hour, if he has intercourse with her, that constitutes taking her back. Allah the Exalted did not allow her to remain in the state of being a woman who can be taken back except for this reason, perhaps he will desire her. For this reason, we tell the woman who can be taken back to adorn herself for her husband, to perfume herself for him, and to be coquettish with him, perhaps he will desire her and take her back. Yes, indeed. Do you know, if Allah wills, when she gets married.
