Sunan an-Nasa'i 2968
It was narrated that Urwah said:
"I asked Aishah about the words of Allah, the Mighty and Sublime: 'So it sin not a sin on him who perform Hajj or Umrah (Pilgrimage) of the House (the Kabah at Makkah) to perform the going (Tawaf) between them (as-Safa and Al-Marwah) and (I said): 'By Allah, there is no sin on anyone if he does not go between As-Safa and Al-Marwa.' Aishah said: 'What a bad thing you said, O son of my brother! If this Ayah was as you have interpreted it, there would be no sin on a person if he did not go between them. But it was revealed concering the Ansar. Before they accepted Islam, they sued to enter Ihram for the false goddess Manat whom they used to worship at Al-Mushallal. Whoever enter Ihram for her would refrain from going between As-Safa and Al-Marwah. When they asked the Messenger of Allah about that, Allah, the Might and Sublime, revealed: 'Verily As-Safa and Al-Marwah (Two mountains in Makkah) are of the Symbols of Allah. So it is not a sin on him who performs Hajj or Urmrah (Pilgrimage) of the House (the Kabah at Makkah) to perform the going (Tawaf) between them (As-Safa and Al-Marwah). Then the Messenger of Allah enjoined going between them so no one has the right to refrain from going between them.'"
أَخْبَرَنِي عَمْرُو بْنُ عُثْمَانَ، قَالَ حَدَّثَنَا أَبِي، عَنْ شُعَيْبٍ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، قَالَ سَأَلْتُ عَائِشَةَ عَنْ قَوْلِ اللَّهِ، عَزَّ وَجَلَّ ‏{‏ فَلاَ جُنَاحَ عَلَيْهِ أَنْ يَطَّوَّفَ بِهِمَا ‏}‏ فَوَاللَّهِ مَا عَلَى أَحَدٍ جُنَاحٌ أَنْ لاَ يَطُوفَ بِالصَّفَا وَالْمَرْوَةِ ‏.‏ قَالَتْ عَائِشَةُ بِئْسَمَا قُلْتَ يَا ابْنَ أُخْتِي إِنَّ هَذِهِ الآيَةَ لَوْ كَانَتَ كَمَا أَوَّلْتَهَا كَانَتْ فَلاَ جُنَاحَ عَلَيْهِ أَنْ لاَ يَطَّوَّفَ بِهِمَا وَلَكِنَّهَا نَزَلَتْ فِي الأَنْصَارِ قَبْلَ أَنْ يُسْلِمُوا كَانُوا يُهِلُّونَ لِمَنَاةَ الطَّاغِيَةِ الَّتِي كَانُوا يَعْبُدُونَ عِنْدَ الْمُشَلَّلِ وَكَانَ مَنْ أَهَلَّ لَهَا يَتَحَرَّجُ أَنْ يَطُوفَ بِالصَّفَا وَالْمَرْوَةِ فَلَمَّا سَأَلُوا رَسُولَ اللَّهِ صلى الله عليه وسلم عَنْ ذَلِكَ أَنْزَلَ اللَّهُ عَزَّ وَجَلَّ ‏{‏ إِنَّ الصَّفَا وَالْمَرْوَةَ مِنْ شَعَائِرِ اللَّهِ فَمَنْ حَجَّ الْبَيْتَ أَوِ اعْتَمَرَ فَلاَ جُنَاحَ عَلَيْهِ أَنْ يَطَّوَّفَ بِهِمَا ‏}‏ ثُمَّ قَدْ سَنَّ رَسُولُ اللَّهِ صلى الله عليه وسلم الطَّوَافَ بَيْنَهُمَا فَلَيْسَ لأَحَدٍ أَنْ يَتْرُكَ الطَّوَافَ بِهِمَا ‏.‏
