Section : Purification For Sa’i.

Most scholars are of the opinion that purification is not necessary for performing Sa’i between Safa and Marwah, in light of what the Prophet (peace be upon him) said to ‘Aishah once when she menstruated. He told her, “You may perform all rites (of Hajj) as other pilgrims do, except performing tawaf around the Ka’bah which you may do after you are clean and no longer menstruating.” (Muslim) ‘Aishah and Umm Salamah said, “A woman who performs the tawaf, offers a two rak’ah prayer (by the Station of Ibrahim), and then finds that her period has started, may perform Sa’i between Safa and Marwah.” (Reported by Sa’id bin Mansur) It is preferable, however, to be in a state of complete purity while performing various rites of Hajj or ‘Umrah, because cleanliness is commendable in Islam.
