Malik said, concerning a woman who entered ihram for umra at the time of hajj, and she arrived in Makka during her period and so could not do tawaf of the House, "When she fears that the time (for hajj) is getting close, she gets into ihram for the hajj and sacrifices an animal. She is like someone who combines the hajj and the umra. One tawaf is enough for her. If a women starts her period after she has already done tawaf of the House and prayed, she does say between Safa and Marwa and stops at Arafa and Muzdalifa and stones the jamras but she does not do the tawaf al-ifada until she is pure and has finished her menses."
