Is it permissible for a husband to take back his wife during her waiting period (iddah) after the third divorce?

If the question is about taking back one's wife during her 'iddah (waiting period) after a third divorce, then it is forbidden to take her back unless she marries another man and he has actual intercourse with her, and then he divorces her. This is based on the Almighty's saying: "And if he has divorced her [for the third time], then she is not lawful to him afterward until she marries another husband. And if he divorces her [the second husband], there is no blame upon them both if they return to each other [through a new marriage], if they think that they can observe the limits of Allah." This is further confirmed by the hadith of 'Aisha - may Allah be pleased with her - concerning the story of Rifaa al-Qurazi's wife.
