It was narrated that Hisham bin 'Urwah said: "My father told me:said to '!ushah: "I do not think there is any sin on me if I do not perform Tawaf. I between Safa and Marwah." She said: "Allah says: 'Verily, Safa and Marwah are of the Symbols of Allah. So it is not a sin on him who performs Hajj or 'Umrah of the House to y,perform Tuwaf between them.'' If the matter were as you say, then it would have said, 'it is not a sin on him to not perform the Sa'y between them.' Rather this was revealed concerning some people among the Ansiir who previously, when they stated the Talbiyaih, they used to recite it for Mandt, and it was not lawful to them to perform Sn'y between Sata and Marwah. When they arrived with the Prophet for. Hajj, they entioned that to him, and Allah :vealed this Verse. By Allah, will not accept the Hajj as complete if one who does not perform Sa'y between Safa and Marwah.' " (Sahih)
