وَإِذَا حَاضَتْ بَعْدَ الْوُقُوفِ بِعَرَفَاتٍ، وَبَعْدَ طَوَافِ الزِّيَارَةِ، انْصَرَفَتْ مِنْ مَكَّةَ، وَلَا شَيْءَ عَلَيْهَا لِتَرْكِ طَوَافِ الصَّدْرِ
Translation: If she menstruates after standing at Arafat and after Tawaf al-Ziyarah, she may depart Makkah without liability for omitting the farewell tawaf.
The dispensation concerns the farewell tawaf, not Tawaf al-Ziyarah. The text explicitly presupposes that standing at Arafat and Tawaf al-Ziyarah have already been performed.
