Answer
Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
Umrah is not obligatory on the woman whose menses starts during Umrah. So, she does not need to worry about it. She can still gain similar rewards by doing other virtuous deeds that she can afford to.
Responding to your question, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states:
Umrah is not obligatory on her in this case. So, she does not need to worry about it. She can still gain similar rewards by doing other virtuous deeds that she can afford to.
The Prophet (peace and blessings be upon him) told his beloved wife, Aishah, “Menses is something that Allah has decreed on the daughters of Adam.” (Al-Bukhari)
And, as Imam Shah Waliullah said, “Islam always provides alternatives for those who are not able to do a particular act of virtue because of reasons beyond their control, and thus through them, they can be blessed with the same rewards.”
In the case of Hajj, however, she can do the tawaf while menstruating-if she is left with no other choice.
Almighty Allah knows best.
