Safwan narrated from Ishaq ibn Ammar, who said: I asked Abu Ibrahim عليه السلام about a woman performing tamattu‘ who begins menstruating before she can perform tawaf of the Kaaba and then proceeds to Arafat. Imam عليه السلام said: "Her Hajj becomes an ifrad (Hajj alone), and she is required to offer the sacrifice of her hady (sacrificial animal)."
