Is it permissible for a woman performing Hajj to circumambulate the Farewell Tawaf two or three days before her return to her homeland for fear of menstruation, according to her calculation, and is it permissible for her to repeat it on the last day if she does not menstruate?

The Farewell circumambulation (Tawaf al-Wada') occurs after the completion of the rituals and directly before departing Makkah, so that one's last act is with the House (Kaaba). If a woman performs the Farewell circumambulation two or three days before her departure, that circumambulation is considered a supererogatory act (nafl), and she must repeat it upon departure if she is not menstruating. However, if a woman menstruates, the Farewell circumambulation is waived for her as a lightening from Allah Almighty, and she is permitted to depart without circumambulating. She does not need to perform an early circumambulation out of fear of menstruation, because if she menstruates, there is nothing due upon her. The proof for this are the hadiths of Aisha and Ibn Abbas, may Allah be pleased with them, which confirm the waiving of the Farewell circumambulation for a menstruating woman.
