Muwatta Malik #862

Yahya related to me from Malik from Abu'z Zubayr al-Makki that Abu Maiz al-Aslami Abdullah ibn Sufyan told him that once, when he was sitting with Abdullah ibn Umar, a woman came to ask him for an opinion. She said, "I set out intending to do tawaf of the House, but then, when I got to the gate of the Mosque, I started bleeding, so I went back until it had left me. Then I set out again, and then, when I got to the gate of the mosque, I started bleeding, so I went back until it had left me. Then I set off again, and then, when I got to the gate of the mosque, I started bleeding." Abdullah ibn Umar said, "That is only an impulse from Shaytan. Do ghusl, then bind your private parts with a cloth and do tawaf."
