“I once asked abu Ibrahim (a.s.), about the case of a woman who performs Tawaf and after the fifth Tawaf begins to experience Hayd (menses). He (the Imam) said, ‘If a woman begins to experience Hayd (menses) when performing Tawaf or Sa‘y between al-Safa’ and al-Marwah after passing half of Tawaf, she can mark that point. (After becoming clean she can return to that place and continue to complete the remaining part of Tawaf) but if she discontinues Tawaf before half of it is complete, she must do her Tawaf all over again.’”
